can't resize ratsnest lines

[whitis]

I hand drew a bunch of rats nest lines and they were too wide (around 8 mils) to allow me to add rats nest lines to the capacitors in the middle of the area covered by the rats net line.

  - Select lines
  - select -> change size -> decrement by 1 mil

Does nothing.

In case you were wondering this was intended as a test of the effect of capacitor placement and orientation on routability.

1) The menu item itself actions on lines and arcs, not rats,

2) There is no ChangeRatSize in the ChangeSizeFunctions

3) DrawRat seems to consider Settings.RatThickness to be the arbiter of rat size, although it only overrides the rat size if it's <20 (which means "width in pixels" instead of board dimensions).

I would advocate fixing DrawRat to always stuff in RatThickness so all rats are equal, and then adding a way to set the rat thickness via actions and/or a dialog.

Here's a bit of magic: the rat-thickness setting (command line or ~/.pcb/settings) is the thickness of the rats in pcb units (1/100 mil) - unless it's less than 20 (0.2 mil), in which case it's in absolute pixels. As you zoom in the rats nest thins out.
