Merge pull request #5271 from dmtaub/adsk-dev-editor

Adding click and clickDone events to TransformControls for Gizmo interaction
Removed three-math.js
WebGLRenderer: Support for BufferGeometry with material.wireframe = true.
Not pretty but better than nothing I guess.
Updated builds.
Editor: Changed default position for lights.
OBJLoader: No more 0 filled normals/uvs.
BufferGeometryLoader: Use addAttribute().
Updated builds.
merging dev, slight fix
