OSD Locking (#794)

Browse Source 
Add osd_lock and osd_lock_time config options
When osd_lock is set it specifies a sequence of button pressed that must be pressed in order to gain access to the OSD while running a core.
osd_lock_time is the time (in seconds) before you will be prompted again for the unlock code after you have closes the OSD.
