Add Google maps-style controls to 3D mapper

[vadi2]

Description of requested feature:

Lets revamp the current unintuitive controls and instead adopt industry-leading practices on how controls for 3D views work instead, inspired by Google maps.

1. clicking and dragging should drag on the current plane
2. ctrl+clicking and dragging should rotate the plane in all axis
3. on-screen compass to help orient
4. remove existing plethora of view control buttons

Reasons for adding feature:

1. More intuitive navigation of the map

Expected result of feature

clicking and dragging should drag on the current plane

Nitpick: the behavior in the video is clicking and dragging translating the focus point on the x/y plane regardless of camera position/axis. I think this is also what we want for the 3D map and I suppose that's what you meant anyway.

I did mean that, thanks!

Nitpick:

2. ctrl+clicking and dragging should rotate the plane in all axis

This is not only true for CTRL but also for SHIFT + drag
