Flags != language See http://www.flagsarenotlanguages.com We now use
local, untranslated language names for all languages.
Languages that have not been updated in >5 years and have less than 15%
of available strings translated have been removed from the menu options.
If a translator steps up to update the .po files, we can re-add them
This allows for the tool framework to keep track of a universal
set of conditions for the UI state (enabled/checked/shown) for
controls of actions. It removes the need for the main menubar
menus to be CONDITIONAL_MENUs and be rebuilt on each open,
and instead makes the updates of the check and enabling of
items handled in the native wxWidgets way.
This commit switchs the 3d viewer and kicad project manager window
over to this system.
