Scripts and Exits updated. Fixed some deep issues with Scripts that caused object-based scripts to not properly shut down in some situations, as well as spawn multiple instances of themselves. I think this should resolve all "at_repeat doubling" issues reported. Due to optimizations in the typeclass cache loader in a previous update, the Exit cmdsets were not properly loaded (they were loaded at cache time, which now doesn't happen as often). So Exits instead rely on the new "at_cmdset_get" hook called by the cmdhandler. It allows dynamic modification of cmdsets just before they are accessed. Resolves issue173 (I hope). Resolves issue180. Resolves issue 181.
