* Added required dependency setuptools to install_requires
* Remove optional dependency ipaddress from install_requires
* Created extras_require in setup.py. The optional dependencies should
not be included in install_requires so that users can either install
forked dependencies or remove problematic ones. Updated documentation to
detail how to install these optional dependencies.
* Fixed README badge

Due to new limitations for open-source projects on Travis we are
switching to GitHub actions.
* Notes about system site-packages
We had many problems with accessing system python packages on Travis for
libtorrent and GTK and the problems are harder on Github since there is
no more access. For now copying the python libtorrent binary into the
deluge source is the workaround. There is a pip package that could be
used in future.
Fixed failing tests with libtorrent 1.2 which required a non-zero length
file in torrent and workarounds for async alert delay.
