The changes include:
* Change license blobs in source files to mention GPLv3+ not GPLv2 only
* Add GPLv3+ license text
* Package COPYING not LICENSE as the license blobs (even the old ones)
mention COPYING specifically, it is also more common, I think

Once this is committed we can start the process of renaming errors2 as errors.
I thought that combinig this into one commit would be more difficult to
review.
We need a way to say "this attribute is blank, delete it." delAttr does this.
There are now several attributes to which we add "members" to so make the
attribute for storing members configurable, defaulting to 'member'
