Added tracking of inactivity in chatbar.

Now indicator will disappear if for 30 seconds contents of chatbar didn't change.

Moved all relevant vars to the typing_indicator.dm
Added 'typing' var, as 'if(!(typing_indicator in overlays))' didn't work and overlays kept being added forever.
Fixed preference toggle feedback being backwards.
Fixed wrong verb called in hotkeys mode.
