Camera controls rework

[kpal81xd]

• Rewrote orbit camera to use pointer events
• Changed right click to orbit around camera (instead of focal point)
• Changed pan to be middle mouse button/holding shift and right click to drag
• Added smoothing to flying, orbiting, zooming and panning (frame rate invariant)
• Fixed panning (doesnt rotate around camera)

Did a quick local test and have a few comments:

• i personally don't like having to switch between the two camera types (and not sure what the win is compared to before)
• orbit camera has no smoothing
• orbit camera right mouse button should pan the camera (currently both left and right buttons orbit the camera).
• mouse scroll zoom is inverted
• frame function resets the camera orientation. it should just move the camera (not rotate it) to frame the current selection. should also have smoothing.
• fly camera rotation isn't smoothed
• i much prefer the distance-based zooming, with smoothing

Added all changes!

Did another quick test:

• 'F' to frame doesn't frame meshes correctly
• dragging any slider on setting popup rotates the camera (check FOV, for example)
• panning the camera doesn't seem to go perpendicular to screen
• panning sensitivity doesn't seem to follow orbit distance (zooming closer in should result in less sensitive panning)
• zooming all the way in to focus point seems to go too far (goes through the target surface)
• zoom button is now very sensitive on my mouse

Awesome! Just a tiny issue with framing then we're good to GO!
