0.2.1 MC 1.16.1, GLFW errors

• Update to MC 1.16.1
• Fix a latent problem with texture object labeling
• Mark mod as clientside
• Add proper reporting of GLFW errors

v0.2.0

Refactored a bunch of internals, overall the Annotater class is now much more pleasant to use: instances can be created at any time regardless of GL context (constructor is preferred now).
Also added texture labeling, and a hook on TextureManager that labels every registered texture with its identifier.
Removed the thread aware stuff as it turned out to be irrelevant to the profiler hooks (its only user).

v0.1.0

Renamed the project to narrow its scope, previously I was considering adding all sorts of other stuff (like GPU timers). Also, there is a MC source class which yarn names "GlDebug".
While at it, rename and straighten out the namespaces to be less stupid. They shouldn't change anymore after this.

Other than that, GlStateManager got some annotations, and the mod got an icon.
