64 bit : interpreter & GSdx Hardware working

Fixes up things so as to get 64 bit building & "working".
Interpreter runs, so does GSdx though only in Hardware( some fixes are actually done for software but someone who knows it better than me will have to finish it as it seems clearly unfinished. It needs to be builld in avx too, as sse2 one is not considered as valid(many methods are empty, it builds but linking seems to fail, don't know why, it was already like that).
SuperVU is removed as it is, according to your own discussions in dev part of forum, not portable and I could not even build with it. As a bonus, build is faster after it's suppressed :)
Fixes mostly include typing, I don't know if I got every last stray "L" before strings going to wxwidget, some of them are even nescessary, the others cause crashes, I probably got almost all reachables, however, if you ever get a crash in wxclen, just backtrace until you have some write to wxwidget that include a "L" prefixed chain.
I will use that as a base to continue the port. I will see if I just port the current frontend/backend(my head ache a little right as I try to understand the code though for now) or if I just make a new one(potentially using qemu as a base then).
