Added different macros, instead of using _MSC_VER. This one is added
even when Clang with MSVC runtime, so it's not viable to check if we're
compiling with MSVC.
Fixed: crash when moving a char in an area full of teleporters, or whichever items made the char move multiple times in the same tick.
Fixed: buffer read past the end in CCacheableScriptFile first reading.
Fixed: if a char had the COMM_CRYSTAL flag enabled, it called ::OnHear on every item in range, without checking if the item is actually capable of hearing.
Further optimized distance checks.
Separated the Github workflows into different files, in order to get a different badge for each build platform/type.
Dismissed AppVeyor build.
Added sphere_library/sfastmath.h.
Fixed twofish compilation error on Windows. That library wasn't really meant to be used as-is...
Made _GITVERSION define macro available only when enabling git versioning from CMake.
Modernized and fixed MSVC CMake toolchain.
Removed mariadb_version.h from git index.
Windows and OS X not yet tested.
Moved toolchains .inc files to include/ folder.
Renamed folder lib/bin into _bin.
Moved bcrypt and twofish library into lib folder and into new cmake projects. Restored twofish library to the original version.
Fixed some format warnings.
