Font object + editing back.

Was quite some work due to a myriad of globals all over!
Works nicely 100% local now.

To enable a single textedit operator, I've added a new
keymap entry KM_TEXTEDIT, which gives all keyboard events
to the handler. Also had to add a new keymap-add function
to force a keymap handler in beginning of region handlers.
In future this can be used to prioritize handlers.

Also: split off the arrow keys (frame change) to a separate
region level handler. Can be set with default flag in
regiontype->keymapflag ED_KEYMAP_FRAMES
