Torbjörn Andersson 4c3a68027f Use the same syntax for accessing script variables as BS1 does, i.e. now
it's Logic::_scriptVars[ID] instead of just ID. Apart from looking cool, it
makes it much easier to tell the difference between variables and constants
when looking at the code.

Of course, this sort of sweeping changes is jolly good for introducing
truly weird regressions, which is why I waited until after 0.6.0.
