CityBuilder Code

The clutter entry class has been added.
The channel info class has been added - expected child classes include the
clutter entry class and the property/lot class.

added description

Added config file support. The config group and attrib classes are from the
MPV project, but the parser is new, and is based on libxml instead of a
custom bison-generated parser.

Finished merging *GeneratorAC3D into GeometryWriterAC3D.
Decided to be extra-daring and rename and modify a file in the same revision
(StreetGenerator3DC).

renamed StreetGeneratorAC3D to GeometryWriterAC3D... plan on merging
BlockGeneratorAC3D and StreetGeneratorAC3D into same class

added ac3d generator for blocks. tested with a simple street layout.

Finished the initial version of the block code.
Added block code to the build system.
Block code seems to work, and seems to pick appropriate blocks. Still need to
finish code to pick corner positions and generate geometry.

moved generateRectangleTexcoords and distanceFromPointToLine to misc.cpp
implemented and tested a new testPointWithinTriangle (not based on the old code)

Restored some binaries that svn corrupted.
Automatic newline conversion is great and all, but not when it fucks up
my files. I have a feeling that cvs2svn is to blame for this.

Nearly finished initial re-implementation of Block, BlockGenerator.
Added 'finished' flag and isAdjacentTo() to GraphVertex
