New Revision: 750

Modified:
   firmware/tuxcore/trunk/ir.c
   firmware/tuxcore/trunk/standalone.c
Log:
* Added a protection on IR RC5 receiver code so that only codes from kysoh's
  remote are considered valid. The IR code needs to be refactored so for now I
  prefer to reject false triggerings rather than try to support usages we don't
  really need right now.
