1.7.2 update.

Only thing not working is the localizations, everything else seems to be
updated.

Also, finally made it so that snow can replace grass, sapplings,
flowers, ect.
More fixes, as well as improvments.

Started replacing some of the ASM with events. It is likely that there
is more that can be done with that.

Also updated localizations and renamed modid.
Lots of improvments. Beware IceAgeMode.

Added code to lay snow more evenly.

Added DeepSnow and IceAgeMode.

Various other improvments related to these things.
Check for Material.vine.

Tall grass seems to use vine instead of plants.
