Namespace Hammer/MapDoc under Tools.MapEditor
Add a simple MapMesh API for creating simple n-gon polygons programatically in tools addon layer
Move Hammer Block tool to C# addon layer, developers can implement any geometry shapes using the simple polygon mesh API and full hotloading.
Ported the following shapes to C# so far: Quad, Block, Cylinder
Cleanup naming of everything, create the tool interface in a more sane way, port over more primitives.
* GeometryTool -> BlockTool, keep the naming consistent with Hammer, it is a blocking out tool after all
* Geometry -> PrimitiveBuilder
* SimplyPolygonMeshDescription -> PolygonMesh - way less insane and future proofs us to binding it with CHammerPolyMesh, different ways to use it can be done on the class
* Port Spike and Hole primitives, Linq makes them super easy to do
* Hotloading triggers an update on the block tool, so when creating PrimitiveBuilders you see the changes straight away
* Glue "Orient to the 2D view plane direction" checkbox to set the option in native
