Removed glass from the list of blocks immune to rifts. That was just a
temporary change so that I could check how rifts were destroying blocks
in a controlled manner.
Made it so rifts destroy blocks in layers rather than destroying random
surrounding blocks, even through indestructible blocks. This resolves
issue #24.
Made rifts check block hardness while replacing blocks so that we can
avoid destroying strong or indestructible blocks from other mods.
Updated references throughout the code to use a function in BlockRift
for this purpose.
Added support for rotating the metadata of powered tracks and detector
tracks. Also made a minor change to DungeonSchematic to protect its
internal state.
Changed BlockRotator so that missing stair types are recognized for
applying rotations. The general code for all stairs was there but the
block IDs for wooden and brick stairs weren't recognized. Also removed a
duplicate reference to nether brick stairs.
Simplified metadata rotation code by only having a single function that
rotates metadata by 90 degrees clockwise and applying it repeatedly for
180 and 270 degree rotations. Removed flipDoorMetadata() from dimHelper
and replaced all references to it with references to BlockRotator. This
makes all our rotations reference a single function. Replaced hardcoded
rotation in DungeonSchematic.
Added support for wood (tree trunk) and quartz pillar metadata
rotations.
