The big plz accept change - Mega Thanks To Gorbit99

On macos, you can't use a wstring inside an fstream

It is what it is :D

He helped me rewrite the sprite loading functions to be compatible, he should get some credit

Thx J. Random Programmer
There are many vk keys apparently, gonna implement them later, let's leave it our for now

-Removed game thread, moved it into main thread (mac event fix)
-Scancode -> keycode (arguably better)
-Draw and fill triangle (compatibility with 3d engine tutorial)
-Implemented left out VK defines (sprite editor compatibility or smthg)

I need mac testers desperately

Added sound and audio

std::atomic<float> m_fGlobalTime = 0.0f; => std::atomic<float> m_fGlobalTime = {0.0f};
thx J. Random Programmer

Added sound and audio into the engine without using additional dependencies, keeping compatibility as much as possible
Also fixed some typos

Added auto UNICODE, and potential Win8 fixes, also enabled OnUserDestroy(). Should now work with certain versions of code::blocks, though untested by me.
