Doomsday Engine

Began separating the map loading code into two phases:

• Read and transform the map data from WAD into an intermediate format.
• Send the transformed map data through an API which reconstructs the map in our native format.

In addition, polyobjects are extracted from the world and do not affect BSP or polygonization of the world. They now exist outside of the global map data structure lists.

Note, this code is very early and there are some issues with this revision:

• "blockmap-build 2" must be set otherwise map loading will fail.
• bias lighting and polyobjects is a bad idea. When playing jHexen, turn bias lighting off as a crash is more than likely otherwise.
