Added breaking animation to all breakable blocks.

Smart preview: only blocks that can be (re)placed show a preview.
Smart outline when breaking: only blocks that can be broken by the current tool get an outline.
Improved occlusion by render further block previews first.
Reversed order of mirror and array to mirror arrays (for roofs etc).
