Use IBlockState instead of Block methods

Browse Source 
There was a crash in RedstoneUtil when redstone state was changing next
to a full block due to the incorrect state being passed. By using
IBlockState methods we ensure that this cannot happen again.

The old IBlockState methods were also deprecated, so this reduces the
warning count a little. I've also moved string translation into
StringUtils, to reduce the number of deprecation warnings from there.
