app: Disable history buffer via use of gimprc option 

Adds non-UI option to disable the use of often buggy history buffer.
This option defaults to false, since a lot of device/X/GDK combos are broken
and the resulting stroke often actually looks better without history events.
Put (use-event-history yes) in gimprc if you want more events and possibly bugs.
