Next release will be 0.1 and it might take a while. It will focus on fixing bugs which don't appear to be fixable by moving the backend to uBO, which is the target for version 1.0.

Functionality:
- Update punycode.js
- Improve solution to ambiguous/punycoded domains
- Add font as a blockable element in the matrix
- Handle beacons as part of hyperlink auditing

Other:
- Add licenses for blocklists where available
- Renames in buildscripts

Temporary fix for #765 using a fix from uBlock (https://github.com/gorhill/uBlock/issues/2550) which in turn uses the fix from Chromium.

Temporary because its not implemented very well, I'm still getting my head around the uMatrix codebase.

Also made the default blocklists less extreme, which should result in less false positives.
