FFE: Setting Ubuntu Font As Default

[Rick Spencer]

Hi all ...

I want to bring this FFE to attention:
https://bugs.edge.launchpad.net/ubuntu/+source/light-themes/+bug/649616

It is my understanding that using the Ubuntu font by default has been
the plan of record for some weeks or months. None the less, given the
time lines involved, I thought it best to raise wider awareness that we
are preparing this change as it is after even RC Freeze.

The change will set the Ubuntu font to be the default in the UI, but not
for documents or monospace. Please note that the FFE has not yet been
accepted.

Cheers, Rick
