Biome Height Tweaker

Built on forge 12.18.0.1982 (use on that version or higher, forge for 1.10 and 1.10.2)

Changes form 0.4:

* Fix check to not inject cave generator multiple times (would have been rare before, this is less of an optimization and more to keep impact to other mods at a minimum, thus its likely never caused a problem, however now is implemented correctly) .. note cave generator will not be injected if alternative cave gen is disabled.

* Spruce villages (if enabled) in ice plans no longer have Packed Ice roads (since villages now spawn with path blocks), instead some of the cobble is now stone bricks.

* Marking this as a Release, since unless forge causes something to break this is release quality.

Configuration files, and seed generation is identical to 1.9.4 so worlds using this mod can be upgraded from 1.9.4 -> 1.10 without issue.
