+ Fixed plenty of bugs in my regular expressions with regard to matching
class, methods, globals, locals, and vars when there were spaces involved.
They are now consistently showing in the autocomplete menu, class explorer,
and object explorer.

+ Split the "FindVariables" method into two distinct methods, one for
matching globals and the other for class members "var".

+ Changed the casing for RPGCode tooltips back to traditional camel casing.

+ Some of the code was refactored
