pixelron additions

- home on a stick now stores info on player, so only one home per person rather than per stick :) no more using other people sticks either.

- reduced the size (polygons) of models, everything is now much smaller, pack is 1/8th previous nonsense.

- added internal text for machines detailing what goes where.

- oredicted prime crystal.

- changed nether star machine model, now looks sick.. or more likely sickening.

- other things to improve load-time that little bit
