Subject: [PATCH] Fix slab descriptions.

A regression caused the description of slabs to revert to the source block's description.  This commit fixes the regression and adds descriptions which were missing for the recently added slabs (two_sides, three_sides, and three_sides_u).

Closes minetest-mods/moreblocks#96
