Pull Request

Brief description.

Introduces an image library that includes general image related functionality. New robust alternatives to current image based features are introduced by this PR.

What Issues Does This Fix?

The image biome provider lacks some functionality, such as non tiling behaviour and manually defined color to biome mappings. These are now provided via the library and implemented in the new image provider.

Affects of the PR

Current image based features are deprecated with the introduction of the library-image addon.

The BufferedImage loader from the common implementation is deprecated, the Image class provided by the image library should be used instead.
