Rework script/subst parser for improved performance
*: Keep abc(def) as a single token, but split abc($def) into 4 tokens
*: Then optimise when interpolating to keep a reference to the underlying objects
*: This speeds up the 'set a($b)' case a lot
*: Also avoid so much alloc/realloc when parsing scripts and subst objects
Also simplify cmdStruct creation
*: Can omit args=-1 for expand
*: Makes it easy to calculate the length
*: Do it all in a single loop for simplicity, size and speed
