key reassignment dialog box

[rob]

GUI for key reassignment. Borrow from PyPE? Should be grouped by major mode, minor mode, and global commands.

(In [2074]) Refs #53: added mode to display key bindings (no editing yet)

• added ListMode? abstract major mode
• added list_menu containing actions for ListMode?

[rob]

(In [2084]) Refs #53: added dropdown list to only select actions with keybindings

[rob]

(In [2086]) Refs #53: added preliminary actions for setting key bindings

• RebindKeyAction? starts the new key binding
• AddKeystrokeToBinding? will be used to append keystrokes to the key binding where RET will end the keybinding
• what to do about trying to bind to RET is still undetermined

[rob]

(In [2088]) Refs #53: added rebinding actions for single and muliple keystrokes

• RebindKeyAction? bookends multiple keystrokes with RET
• single, two, and three combinations can be entered using keys 1 (or SPACE), 2, or 3, which is also how a keystroke is entered that contains a RET or SPACE
• added KeystrokeRecording? object which handles calls to setQuotedRaw
• changed ListMode? to use actions and added convertRawValuesToStrings

[rob]

(In [2091]) Refs #53: added save capability to Keybindings

• used new file write interface of STCInterface
• moved remapped actions into KeybindingSTC
• no changes are made until the save action is called
• still pending to reload the keybindings for the mode

[rob]

(In [2096]) Refs #53: Fixed problem with sorting keybindings

• ColumnSorterMixin? needs itemDataMap to have one entry per column and the getListItems wasn't doing that.
• added ActionSortWrapper? within getItemRawValues to add a layer of abstraction around the action but still have the action available to getFirstSelectedAction when it wants to find out the index of the event without maintaining a parallel sorted list
• removed convertRawValuesToStrings

[rob]

(In [2097]) Refs #53: fixed getListItems to point to remapped_actions inside stc instead of mode

[rob]

(In [2098]) Refs #53: added filtering of actions by major mode

• modified UserActionClassList?.getActiveActions to be a classmethod and callable from the outside
• added pulldown in KeybindingMode? listing major modes
• added checkbox in KeybindingMode? to filter out any actions that also appear in EmptyMode?, thereby filtering out global actions

[rob]

(In [2102]) Refs #53: added undo/redo to the key assignment mode

• referenced new UndoMixin? in the KeybindingSTC
• added CanUndo?, Undo, CanRedo?, Redo to the KeybindingMode? that forwards requests to the STC

I think that's probably enough for a first cut at a key assignment dialog box. I'll open other tickets for enhancements as they occur.
