Hi,

I've been working for a while on an improved outline editor tool, with
following features:
- arc/polyline/circle support (so far)
- chamfering & filleting
- snapping to characteristic points of other board features (mechanical,
pads, components, etc.)
- constraints (similar to CAD packages, e.g. Solidworks)

Henner, if you're interested, I can push my current code (it's a mess)
to my github.

It won't be ready for the V5, but I'll commit it to the nightlies as
soon as V5 is out.

Cheers,
Tom
