Continuing from #309, which was mostly focused on 306/307.

308:

• Update.esm should not be written into plugins.txt for Skyrim LE and newer games (including Enderal). The game hardcodes it to load directly after the game master. Done in 1b412e1.

309+:

• expose saved load orders/active plugins lists and allow the user to edit them - a lot of thinking this needs (UI ?) -> new issue Expose saved load orders #361
• revisit undo/redo -> clean invalid ? More traditional undo redo (remove redos on a new load order)-> will be investigated as part of issue Expose saved load orders #361

Ut:

• ccc file handling fixups - see Non-issue reports and notes (view) _> new issue CCC fallback isn't accurate to game behavior #682
