Build fixes

[ScoreUnder]

1. Updated CGLM which seems to fix a lot of people's issues with mismatched vector types
2. Gave make a clearer chain of dependencies and the files we expect from them re. library compilation
3. Moved the game target up to default position and removed all
4. Gave the game an order-only dependency on the bin directory (meaning it doesn't get rebuilt every time if that isn't necessary)
5. Used the compiler's dependency tracking (-MMD, supported by at least gcc and clang) to allow incremental compilation

It's not perfect (I haven't properly inspected the dependencies of the libraries and triggered recompilations of those where necessary) but it should be enough to enable parallel builds and somewhat reliable incremental compilation.

Thanks! I got it running with your help. I tried multiple different variations of below but it was the only way I got it working.

My steps to get the game compiled was as follows:

1. git clone --recurse-submodules git@github.com:jdah/minecraft-weekend.git
2. cd minecract-weekend
3. make (original Makefile)
4. make game (original Makefile)
5. cd lib/cglm and delete all files/folders.
6. git clone git@github.com:recp/cglm.git .
7. cd ../.. (should be back in minecraft-weekend folder)
8. copy your changes to Makefile.
9. run make.
