template initNimRuntimeVars(): untyped

This should be called on initialization.

The Game Boy RAM is initialized to random values on bootup. We can just dive in if we're using an emulator that initializes everything to 0, but on more accurate emus and real HW things will go bonkers, because there are a couple of global variables = static allocations that Nim considers when running the program and these need to be cleared out first before doing anything.

I should point out that NimSkull does this stuff automatically, but I'd probably need to make a separate version since they do not support patchFile and such other "frivolous" things... yet?
