amulecmd.1: don't translate command names in section headers - #547

The Spanish manpage catalog was already brought up above po4a's 80%
threshold for amulecmd.1 in #547; this commit completes the parity
with the it/fr/de translation passes in this PR by adding the two
remaining strings the other languages got:

  - amule.1:45 / amuled.1:53 -- the new --disable-fatal description
    added upstream around the same time the search-filters block
    landed in amulecmd.1.

  - amulecmd.1:140 -- the previously-fuzzy "A synonym of..." entry.
    The Spanish translation was already correct ('Un sinónimo del
    comando B<exit>.'); only the typo 'synonim' -> 'synonym' changed
    in the English msgid, so just removing the #, fuzzy flag is
    sufficient (no AI marker since no translation change).

The deeper backlog of pre-existing Spanish translation gaps (~46
amulecmd/amulegui/amuleweb/ed2k/alc/alcc/cas/wxcas strings that have
been untranslated since long before this PR) is intentionally left
for a separate "fill backlog Spanish gaps" follow-up to keep this PR
focused and per-language commits comparable in scope.

The --disable-fatal translation is marked `# AI-GENERATED -- please
review.` for a native Spanish reviewer.

Regenerated amule.es.1, amulecmd.es.1, amuled.es.1 via po4a 0.74.

The amuleGUI "aMule Log" tab appended the daemon log one line at a time.
Each AppendText auto-scrolls the bottom-anchored wxTE_RICH2 control, so a
first-sync backlog of thousands of lines paid an O(n) RichEdit reflow per
line and visibly churned the scrollbar (what reads as forced "smooth
scrolling"), taking ~20 s for a ~16k-line log. Coalesce each poll's lines
into one AppendText per bold/normal run (FlushLogBatch) instead of one per
line.

On Windows the log view (which lives on the Networks page) also renders
wrong when the backlog arrives while that page is hidden -- the default tab
on launch is Transfer, so a hidden wxTE_RICH2 never lays out and comes back
showing only the last few lines until a manual scroll. Defer the scroll +
repaint to the next page-show, armed only when lines actually arrived while
hidden, so a user who scrolled up and switched tabs keeps their position.
When the page is visible, force a Refresh()/Update() after the scroll.

Addresses points 1, 2 and 5 of amule-project#547.

The amuleGUI log panes used a wxTE_RICH2 (RichEdit) control, which holds the
whole document and reflows O(n) on scroll. A remote-GUI first sync can dump
tens of thousands of daemon-log lines at once, so scrolling crawled and the
view mispainted -- only the tail visible until a manual one-line scroll
(issues amule-project#445, amule-project#547).

Replace the three log/info panes (aMule Log, aMuleGUI Log, server info) with a
new CMuleLogCtrl backed by wxStyledTextCtrl. Scintilla renders only the
visible lines, so scrolling and full-history retention stay O(visible) at any
size, and unlike a virtual list it keeps character-level selection and find.
Critical lines are bold via per-line Scintilla styles; the view tail-scrolls
only when already at the bottom, so scrolling up to read history sticks.

This removes the whole RichEdit workaround stack -- the per-poll append
batching, the deferred hidden-page scroll, and the Freeze/Thaw lineage from
amule-project#451/amule-project#471/amule-project#477 -- none of which Scintilla needs.

wxStyledTextCtrl (the stc component) ships with the wxWidgets packages every
platform already builds against, so it adds no new dependency; it is requested
only for the GUI library that owns the log views.

is hidden (its notebook page or sub-tab is not selected -- e.g. the first-sync

the first idle once the pane is on screen. This lives in CMuleLogCtrl, so all

The deferred/tail scroll called ScrollToEnd() directly. With word-wrap on --
where Scintilla lays out wrapped lines incrementally over several idles -- two
problems fell out:

- switching to a hidden log pane after the backlog loaded landed a few lines
  short (the single scroll ran before the tail was wrapped); and
- switching to it mid-load landed at ~90%, because the batch tail-scroll and
  the idle re-scroll loop both moved the view and the loop misread its own
  batch scroll as a manual scroll and gave up.

Make OnInternalIdle() the sole scroller: ScrollToBottom() only sets a pending
flag, and the idle loop re-applies ScrollToEnd() until the first-visible line
stops moving (wrap settled at the true bottom), bailing only when the view
moves on its own (a real manual scroll). Appends never move the first-visible
line, so the loop follows the growing log through the whole replay. Lives in
the base CMuleLogCtrl, so all three panes (aMule Log, aMuleGUI Log, server
info) share it. Follow-up to amule-project#548 (issue amule-project#547).

Follow-up to amule-project#548 (Scintilla log panes). The tail-scroll landed short when log
lines wrap, because Scintilla lays out wrapped lines incrementally over several
idles, so a one-shot ScrollToEnd() ran against a display-line count that did
not yet include the still-unwrapped tail. Switching in mid-load made it worse:
each poll's batch also scrolled directly and the idle re-scroll loop misread
its own batch scroll as a manual scroll and gave up (~90%).

Make OnInternalIdle() the sole scroller: ScrollToBottom() only flags a pending
scroll, and the idle loop re-applies ScrollToEnd() until the first-visible line
stops moving (wrap settled at the true bottom), bailing only on a genuine
manual scroll. Appends never move the first-visible line, so it follows the
whole replay. In the base CMuleLogCtrl, so all three panes share it. Also
corrects a few amule-project#548 comments the rework left inaccurate. Reported in amule-project#547.
