This partially reverts 36d36de and 3bac100, moving the legacy footprint
lock/unlock code from the autorouter (which remains disabled) to
pcb_edit_frame.
This had been removed along with autorouter but its functionality is
still desired. If/when the autorouter is resurrected, these IDs will
need to be deconflicted.

Some changes (enable/disable a layer) set the dirty bit even for empty boards.
So when closing pcbnew, the dialog asking for saving the board was shown, even when no board loaded.
Frame, dialog and config file couldn't agree on whether to use
internal units or not.
Frame now stores internal units, and they're now mapped on the
way in/out of the config file. Dialog was already assuming they
were stored in internal units (though they were previuosly not).

Also adds indicators in layers palette for feedback.
Also generates sized images for all indicators instead of using
scaled bitmaps (which didn't look great).
Also fixes a completely unrelated typo in a UI string.
Includes some dialog changes to go with the menu update.
Includes promoting the Pcbnew graphics mode back to main menu.
Includes renaming Graphics modes to Toolsets.
