Subject: [PATCH] CON: Add EVENT_DISPLAYCAMERAOSD. Set RETURN to -1 to disable
 it.

From this event, if "getactor[THISACTOR].htg_t 0" is zero, then the camera is functional. Nonzero values indicate the camera has been destroyed, which is only possible when the CAMERASDESTRUCTABLE parameter of gamestartup has been enabled.
