Fahcontrol no longer installs on Ubuntu 18.04 or 20.04

[ipkh]

Please update fahcontrol to work on modern Ubuntu and its derivatives. Please update bindings to python2 and ftw3. Python2 and gtk2 are end of life and no longer supported.
A warning on the folding at home download page that fahcontrol only works on Ubuntu 16.04 variants would be helpful.
Maybe update the web control component to support advanced control options currently available via fahcontrol.
It does not seem untenable to expect support of major OS releases every few years.
