[Positioner] Autocalibration: signed angles
...
This commit changes the way the APs are selected. Until now, the two
most acute angles were selected. Now, the angles are signed, i.e. we
differentiate the APs that are before the point to generate on the
trigonometric circle, and those that are after.
Some more refactoring was achieved, and some bugs fixed.

The variance is now computed along with the average. Measurement has
three new attributes:

In addition, average_ss has been renamed average_dbm (ditto for its
getter).
The computation method of the average has been changed to allow the
computation of the variance simultaneously.

Rename Positioning -> Positioner

To be consistent with the other modules, the positioning server must be
called OwlPS Positioner instead of Positioning, and the executable
owlps-positionerd (even if the daemon mode is not implemented yet).
That's a big commit for a tiny change.
