Implemented lilypad placement
Added MetaRotate/Mirror Support for a number of classes.
Changed Rotater to Rotator.  Added partial sign post rotation support.
Fixed spelling; Rotater to Rotator.
Added a comment about the behavior of doors under mirros.  Simply put, the current implementation of MetaMirror causes glitchy behavior.  The door class itself needs to be edited. (I've got an idea on that....)
Fixed Minor typos.
Altered the rotates for cBlockSignHandler.  The functions as a whole is still unfinished though; no wall sign or mirroring support yet.
Initial NetherFortGen import.

Simple fortresses of 2 different rooms will generate.
Merge branch 'master' into NetherFortGen
Sponged the netherfort balcony prefab.

This is a preparation for the msSpongePrint merge strategy, used for imprinting most prefabs. It will carve out even air, but will ignore sponge blocks.
Fixed a memory leak in NetherFortGen.
NetherFort: Added BalconyTee2 prefab.
Implemented the msSpongePrint merge strategy.

Similar to msImprint, but allows prefabs to carve out air pockets, too. The sponge block is used as the NOP block.
Fixed non-virtual destructors warnings.
Merge branch 'master' into NetherFortGen
Added Prefabs to *nix builds.
NetherFortGen: Added several more prefabs.

Also extended the defauls MaxDepth value to 12.
