Mostly just the result of running `blender_icons_update.py` without adding or changing any icon source files. Removal of three unused icons and adding three others to the project to resolve conflicts between them.

I had to make the viewport navigation icons a bit smaller in the SVG since
the edges were being clipped off, we only support 16x16 icons currently.
They are a bit blurry because of this.
