MxDirect3D (#114) 
* MxDirect3D Constructor

* Implement MxDirect3D::Clear (not yet matching)

* Match MxDirect3D::Clear

* Building out MxDirect3D, link dxguid, add size asserts

* Move a few things around on the Enumerate context obj

* remove dupe mxdirect3d

* Match BuildErrorString and _DoEnumerate

* Fix style
