the stb libs, miniz and minizip are now always optimized to speed up performance, esp. level loading times, in debug builds. So far the stb libs implementation were dragged into the source file that uses them, now I created additional source files just for them so those can be optimized while the engine source files using those libs can remain unoptimized in debug builds.
