Filtered

The mesh filtering system is in place, now all that are needed are some of the filters. Catmull-Clark mesh smoothing is already in place, smooth group edge hardness will be pretty easy to do, the hardest one is MapXForm where I'll need to link the texture generators result into the mesh system. After that's done the material system needs to be finished, import/export added and the modeler is finished. This can be done before the end of the month.
