Merge branch 'master' into feature/Block_Sortivator
updating feature/blockSortivator
added alt side texture for GrowthBlock
the side textures now change depending on wether the block ontop is an instance of GrowthBlock or else. it uses the function onNeibourBlockChange to cause this.
(hours of tinkering, blocked by not understanding flags |:()
Reduced lag on placing GrowthBlocks
had a flag set that made the blockupdate call twice.
also cleaned up unused functions and comments
Merge pull request #2 from Gnomorian/feature/Block_Sortivator
