Gerudoku Genesis (Formerly Tydoku)

This update has been spread out over a few months, so I'm a bit hazy on what was added, but here is some of the more important and recent stuff:

• Red sandstone and red chiselled sandstone
• Made top part of double tall grass invisible but the bottom part is a bit taller than ordinary tall grass
• Added new poppy texture 
• Added alternate textures folder (Feel free to swap any textures)
• More stuff which I forgot as I did it a while ago.
