This allows breakpoints, memory views and watches to be controlled from the GDB interface.  The VBA-SDL-H2 commands can be entered via the GDB monitor (type "help" into the monitor for a list of commands).  Made minor changes to the GDB interface so that the GDB port does not need to be entered every session.  A "Break on Load" option has been added allowing GDB to be connected before the ROM starts executing.
