In-source builds are pain and suffering and I am going to stop people
from doing them to save them that pain.

It still won't compile correctly. But this should avoid the error
messages related to it.

This fixes generation with USEASM enabled.

Core and SDL2 are two separate targets now. Core is a static library
that is linked into SRB2SDL2. The sources for both are separated.
When using an IDE like Visual Studio or Xcode, the source code
organized into groups that explain what that group of sources does.

In the future, "Main" could be split into a few more groups based on
file prefixes, but I think the way it is set up works for now.

Makefile targets are not affected by source_groups and typing `make`
will automatically compile both the "Core" library and SRB2SDL2
itself.

Only when actually making the debug target though!

Tested to work on MSVC, mingw-gcc

Enables ASM-NASM and adds tmap*.nas to sdl target.

No idea if this actually works.

snprintf is now available in MSVC 2015!

this is done as a POST_BUILD step

wow i'm stupid

on non debug, check assets folder in src as well

string.c, capitalization, find fixes

silently fixing a bad malloc here too shhhhhhhhh

Generates zips only at the moment

running is another story

Also support dynamic/static opengl switching

It is really messy at the moment. There is no support for copying the
necessary frameworks and dylibs out to the bundle for distribution, and
it is a frankenstein of manual find_library and find_package which can
sometimes pick up Homebrew dylibs.

Compiles the SDL2 target on Windows successfully

Make sure clear_conditionsets feeds in 1 to MAXCONDITIONSETS instead of 0 to MAXCONDITIONSETS-1, so that M_ClearConditionSet can use them all properly AND clear all condition sets properly.

Apparently the mistake also caused myargc to be cleared in Linux64 SDL2 (as pointed out by that ilag11111 guy on GitHub), so that should be fixed now too.
