Log message:
Take advantage of VarModifiers_Apply, which can parse a variable spec
and expand it directly, without needing a variable context.

Use it in Var_SubstVar, so that .for loops values don't need to be entered
into any context nor looked up.

This speeds up .for loops some, and avoids nasty variable capture
side-effects.

Ok'd millert@, miod@, naddy@   (naddy spotted a problem with the first
version of that change).
