GAME/EDITING: DISABLE_SELF buggy

[Gambit37]

I've mentioned this in other threads, but thought I'd post it as a general bug:

DISABLE_SELF is allowed by your editor George for everything. Yet it only seems to work for wall items.

I've tried it on other things, and it crashes RTC if you use it:

1) On counters
2) On relays
3) On floortriggers

The strange thing is, on floortriggers, the trigger works the first time, but RTC bombs out if you enter the tile a second time.

Fixed for V0.29
