Magic Cube

Only compile the Full, Normal & OIT programs when they are actually needed.

Take advantage of recent improvements to the library and stop allocating a queue of 4 FBOs - even if we are running on a Mali r12.

Merge remote-tracking branch 'origin/deferred-mesh-jobs'

1. Conflicts:
2. src/main/java/org/distorted/objects/RubikCube.java
3. src/main/java/org/distorted/objects/RubikObject.java
4. src/main/java/org/distorted/objects/RubikPyraminx.java

Smaller (and of better quality!) meshes.

Read the meshes from .dmesh files (rather than compute them dynamically).
This (along with single-mesh mode) hopefully makes the rendering much faster, while keeping the time needed for Object Change low.

The only downside: this increases the size of the release APK from 6 MB to 9.6 MB.

Speedup for rendering: cubes 2,3 contain better quality cubit faces (more vertices) than cubes 4,5.

Convert the PostRender to a PreRender, called before we render.
This makes more sense as this way things are prepared for the very first render.

Bugfixes.

Improve rotations of the Pyraminx.

Port changes to ObjectList from the deferred-jobs branch.
