Bug Fix Release: Performance Improvements

Performance Fixes:

Sphere primitives were slowing down the framerate, especially using max vertices. There is still room for improvement, but this has been sped up and should be fairly quick now. Tested 100 FPS on an i7 with a GTX 970.
Deletes should be much faster now.
The wireframe subsystem has been completely overhauled. It is now a shader, which means 100% GPU. Big win for performance, but the triangle normals look pretty cool now too as they're thin little pyramids rather than simple lines.

Bug Fixes:

Fixed bug where scaling an object down, adding a sphere, then switching to triangle select yielded oversized triangle selection outlines.
