Extended event infrastructure so that setting default events is determined

by the system-specific OSystemXXX class.  This is accomplished by overriding
certain methods in OSystem, and removes the need for numerous #ifdef's in
EventHandler.  In simpler terms, pressing 'Defaults' in the EventMapper
now uses defaults which are custom-defined to the specific port.

Added ability for joystick buttons to emulate axis events (and therefore
act as mouse events) for the internal GUI.  Some devices such as PSP and
GP2X don't have a directional pad, and send directions as button events
instead of axis events.  By overriding a method in OSystem, one can now
specify which buttons (if any) to treat as directional.

Added ability to remap the 'increase/decrease volume' events.
