Misa 4bf5e5e6a0 Optimize recompilation from changing commit hash 
This reworks how the commit hash and date are compiled so that if
they're changed (and they're changed often), only one source file needs
to be recompiled in order to update it everywhere in the game, no matter
how many source files use the hash or date.

The commit hash and date are now declared in InterimVersion.h (and they
need `extern "C"` guards because otherwise it results in a link fail on
MSVC because MSVC is stupid).

To do this, what now happens is that upon every rebuild,
InterimVersion.in.c is processed to create InterimVersion.out.c, then
InterimVersion.out.c is compiled into its own static library that is
then linked with VVVVVV.

(Why didn't I just simply add it to the list of VVVVVV source files?
Well, doing it _now_ does nothing because at that point the horse is
already out of the barn, and the VVVVVV executable has already been
declared, so I can't modify its sources. And I can't do it before
either, because we depend on the VVVVVV executable existing to do the
interim version logic. I could probably work around this by cleverly
moving around lines, but that'd separate related logic from each other.)

And yes, the naming convention has changed. Not only did I rename
Version to InterimVersion (to clearly differentiate it from
ReleaseVersion, which I'll be adding later), I also named the files
InterimVersion.in.c and InterimVersion.out.c instead of
InterimVersion.c.in and InterimVersion.c.out. I needed to put the file
extension on the end because otherwise CMake wouldn't recognize what
kind of language it is, and I mean like yeah duh of course it doesn't,
my text editor doesn't recognize it either.
