macOS Support & AppPlatform Cleanup (#57)

* macOS Support & Cleanup

* Fix malformed comments in build-wasm.bat

* Emscripten Fixes

* * Add shebang to the grabsounds.py script

Since it was changed from rw- to rwx, I'll add the shebang so that it actually runs properly.

* * Re-add the patch_data and readme files.

* * Remove sound data.

* Fix some more things.

* Think it's ready to pull now...
