Improved freelook

- Fix movement input affecting all viewports even when clicking outside
- Freelook up movement is now relative
- Prevent tool shortcut conflict when moving
- De-hardcode tool shortcuts (select, move, rotate, scale, wireframe)
- Movement speed depends on zoom distance (like panning)
- Mouse wheel controls speed (Blender-style) due to above point
- Added zoom distance indicator, hides after short delay
