canUseTopic() strip panel, take 2.

The strip panel will now use canUseTopic().
Cyborg and AI canUseTopic() procs will now include a BE_CLOSE variable, just in the case of having to be near the atom.
Added a BE_CLOSE and NO_DEXTERY define, they are both 1.
Third argument for canUseTopic(), dextery check, if a monkey or alien or whatever can perform the action.
