Add two new wire forms

[wawuwo]

Hi! This PR enhances wire laying by adding two new ways to create (or "routes to lay") a wire in addition to two that already present.

These two are available right now:

    From o---+
             |
             o To

    From o
         |
         +---o To

These two become available with this PR:

    From o---+
             |
             +---o To

      o From
      |
      +---+
          |
          o To

The way the wire is laid out is changed with right click while drawing a wire

Thanks for the contribution! Please fix the build error. Some files still referencing wire_planner.hpp while the PR contains wire_planner.h

I made a mistake while organising commit history, now it's fixed :)

I have found a crash. Try to draw a closed loop from wires and you will get a crash at the following point:
