Wrapping it up for a stable release

[Sami]

Seems like all the most critical bugs have been fixed by now and 3.70 beta has been around for such a good while that we don't expect any nasty surprises anymore. So wrapping things up for 3.70 stable starts now, and the release is expected early this month.

The few latest additions to 3.70 that were finally accomplished are craftable cords and ropes from yarn, and whole lotta new character portraits.
Just a little more work and patience is needed and then it's out.
