Porting to Qt5
Two main changes for this version :
- porting to make it work with mercurial 4.7. As a result, at least mercurial 4.6 is required. Otherwise, please use hgactivity-2.4
- porting to PyQt5, (py)Qt4 has been obsolete for long now
As usual, you can clone/update your repository, or download a tarball from the 'file' tab, up-there.
