Adding Mac dylib and SDL2-CS.dll.config to the test project.
Tweaking test code to do an individual function load (to give some test coverage to that method) before loading all function pointers.
Made GLCSGen by default have all GL files in a given project share their delegates and function pointers in a central interop class to reduce assembly size. This brings GL-CS.dll down from about 5.4MB to 2.4MB and GLES-CS.dll from about 500KB to 240KB.
GLCSGen can be run with '--isolated' to generate files the old way for people who want one very specific version as it will be smaller in that case.
Fixing code gen for LoadFunction to use BindingFlags.Public in non-isolated versions.
Added read me to explain the hackiness of the GLCSTest app.
Updated libSDL2-2.0.0.dylib to a version that actually works with Mono.
