preprocessor.py
Also bump the extras submodule to a version of pokemontools with a
suitable version of the preprocessor. The changes from 'master' for
preprocessor.py have been inserted into pokemontools prior to the
submodule bump.
this fixes a lot of previous hacks
first off, rgbds requires that labels from includes be marked as globals.
instead, 3626ddeb stuffed includes into the parent file in the preprocessor.
this meant one huge file got preprocessed every time, adding an additional
ten seconds to compile time.
running the preprocessor once for each file would create too much overhead,
so a list is fed into prequeue.py, which then makes calls to preprocessor.py.
this paves the way for compiling source files separately some day.
next, compiling previously required `make clean` to be executed first.
f3340de6 touched main.asm to force a fresh compile instead. this behavior
has been reverted. now, `make all` will only attempt to recompile if a
source file has changed.
preprocessor.py has some marginal changes. prequeue.py is created to keep
the original functionality of preprocessor.py intact. so many files are
preprocessed on first compile (1951 as of this commit) that the prequeue
call has been hidden.
compile time is reduced to 15-30 seconds on first compile, and 5-10 seconds
subsequently. the majority of this time is spent in rgbasm.
