Update to 0.59 (latest commit)

- Change MASTER_SITES to GitHub, where upstream moved
- Apply some patches from the GitHub Pull Requests to make the port build
  (upstream seems to lost some files while migrating to GitHub) and patch
  some bugs
- Set licenses
- Upstream does not tag releases on GitHub, so it's all guessing what the
  real version is. 0.59 is what I found in the source code.
- Install examples; they are useful to test if the port is working
- Remove old patches, they are no longer needed
- Update WWW
