Ghost of #259 - there are bugs:

308:

• currently renaming multiple installers is broken:

    Traceback (most recent call last):
      File "bash\gui\events.py", line 165, in _post
    	result = listener(*listener_args)
      File "bash\basher\__init__.py", line 2421, in OnLabelEdited
    	name_new = self.new_name(newName)
      File "bash\basher\__init__.py", line 2448, in new_name
    	renaming_type = to_rename and type(self.data_store[to_rename[0]])
      File "bash\bolt.py", line 1125, in __getitem__
    	return self._data[key]
    KeyError: bolt.Path(u'lololi.7z.rar')
  

yep it's not there we just renamed it

• screens have various glitches -> mostly fixed in 020404e
• renaming bak files (a complex thing) must be implemented (a lot of ad hoc code, overrides etc) -> 5a985d8
  • _handle_left_down still checks for u'(autosave|quicksave)' -> acc5a05

310:

• validation of user input needs much work: TODO commit -> 689bc48

model:

• try_rename needs more work to chop off more overrides - and probably needs @conversation - mostly done in 0a69959 and finalized in 1ddf7a1
  • refresh code should be guarded for exceptions and have a base method that takes the output lists of try_rename - see 0a69959
  • especially screen info (so we move the GPath handling to the model) - see 1ddf7a1 and 098836b - still WIP but see comments in 098836b
• (un)ghosting does not properly abort if the file we want to add the .ghost extension to is locked -> still valid?

.. but most importantly the model is half baked - the handling of the names (new name and co) belongs to the infos, handling of the messages to basher and so on - blocks #543 - renames are all about those keys (surprise!) and the handling should be centralized. For final comments and some ideas for a complete rename model see 098836b

That being said this is the final renames issue - we want to discourage people from renaming stuff (apart from installers) mods/saves names play a role and hence the monumental complexity of this code. So with this merge we forget about renames (no, no ini tweaks renames, thanks)
