Added documentation to updateTexture in GT_MetaTileEntity_Hatch.

Added a function to GT_Utility called addTexturePage(byte page).
Added information about who is using which texture page in GT_Block_Casings1.
Updated GT_Block_Casings5 & GT_Block_Casings8 to utilise texture page 1.
Updated Large Chemical Reactor to reflect this change, now also uses Page 1 Index 48.
Moved the Pyrolyse oven casing index from 111 to 22, which is currently unused and within the Gregtech index space.
