1.3 Update:

Browse Source 
- Blitz functions are callable using __stdcall, use it instead of using tailored asm.
- DLLs that rely on this DLL no longer have to load the DLL to call Blitz functions, just include BlitzPointer.h and use the typedefs BP_BlitzFunction#_t.
- Removed Hybrid support until Hybrid is open-source.
