0.2 -> 0.3:
----------

added support for sending key press events.

0.3 -> 0.3.1
------------

1) changed the compilation of root_send. a bit more optimized now.
2) chaged the configuration file parsing.
3) fixed a minor issue with gesture effects. now mouse wraps back to the
   original window where the gesture was started, performs the action, and
   wraps back.
