Fixes another crash bug where during UVLModelLoader loading, it tried to apply tint but couldn't, because no block was available.
Also fixes a bug where the quad tint wasn't propagated and tinting didn't work.
- Compile error fixes (blame @biggles2206). Fixes#53.
- UVLModelLoader is now cross compatible with vanilla (vanilla can use
uvl parents who have vanilla parents).
- Due to it, now using uvlMarker instead of .uvl.
- General code reformatting and cleanup.
Implemented automatic rotation for all tile blocks. You can still use
facing properties in model files, if you want to.
Also, some added some fixes and improvements.
