Separate the func import count from the var count

Still doesn't actually load the variables imports, but at least it won't skip a bunch of funcs and break even worse.

The vars, I need to find a game that uses them... but at least this explains the number neatly, matches JPCSP, and even matches the export structure.  So it seems right.
