Overview of Changes

1. Fixed bug with GNU Library not being recognized as GNU Library General Public License, version 2.0. The name GNU Library is an old alias for this license - you can verify it at the GNU website.
2. Added UPL-1.0 license, which is a very permissive license similar to MIT (see at tldrlegal). The most important difference is that UPL-1.0 includes an explicit patent grant and clear ability to relicense on either the same or other terms. In types, I included it after other permissive licenses compatible with GPL (in the compatibility matrix too).

Reviewer Focus

It would be worth double-checking changes made to the compatibility matrix - I've set UPL-1.0 in the same way as MIT was there.

Additional Notes

The problem with UPL-1.0 and GNU Library can be easily reproduced by issuing the check presented below, which will in result warn about unrecognized licenses.
