Measurement tool - Suport for compass mode

Dear developers,

While creating an orienteering map, I found the measurement tool to be quite unintuitive to use. I would like to have a compass like angle measurement. That means in addition to the current mathematical model which counts angles from East-anticlockwise, to be able to count angles from North-clockwise.

A workaround to achieve my goal is by using CTRL-drag from starting point towards North, and then drag the northern point to the destination point. This counts angles 0-270 as expected but 270-360 angles are appearing as negative values from the Northern point, which is something I have to correct by hand.

I would like a measurement tool with three nodes. A central node where the angle is, a node which sets one side of the angle as a start of measurement [it could be "hidden" (not measuring angles), "predefined" (North, East), or "last position"], a node which sets the other side of the angle (or measuring just the distance if the previous node is hidden). Complementary angles should be able to appear by default or as an option. All numbers should appear internal and closer to the angle when possible.

Thank you.
