Mike Fricker 3b8eff823d Mesh Editor: UI improvements
- Renamed lots of UI text and tooltips to improve UX
- Hid the 'Propagate' and 'Per Instance' buttons until this feature is properly supported
- Flipped radio buttons so they're on top of 'instant' buttons
- Renamed 'Any' to 'Mesh' in the top level UI (meaning, 'any part of the mesh')
- Added group name title text for 'Mesh', 'Polygon', 'Edge', 'Vertex'
- Reversed order of top level buttons, removed 'Select' label
- 'Remove Subdivision Level' now greys out if there is nothing already subdivided
- Fixed lots of non-unity build issues
