New global number variable types

How about adding more number variable types? Right now it's only integer, and I think many people would benefit from adding an option to choose a var type, like int, long, double etc. instead of just "number", if someone wanted to work on bigger numbers than 2 147 483 647.

If not that, then maybe add an option to lock workspace source files? I kind of know how to change the variable type, tho mcreator overwrites workspace files, so it makes it impossible.
