2. Whole bunch of pointless casts removed
3. Unused variables removed
4. Fix bug caused by JP on April 25, 2015 where strings were adjusted for translation and the hotkeys section table accidentally swapped the footprint editor title with tag, resulting in "footprint editor" being exported instead of "[footprinteditor]"
No functional changes besides #4, technically it'll "break" imports hotkeys files but April 25 broke imports as well.
Fix a i18n issue in field names when loading a component, if the language was changed during a session, and kicad not restarted (see Bug #1448654).
However changing the language needs restarting kicad, in order to have all messages or menus translated.
