Gustavo Iñiguez Goia 0aef656c42 ui: allow to use GUI themes
Now the user can personalize GUI's appearance (#424).

There're 15 default themes, dark and light, that will help integrating
on some environments (#303, #335).

More themes can be added, by creating a new xml under
~/.config/opensnitch/themes/ or
/usr/lib/python3/dist-packages/opensnitch/

The lib used is https://github.com/UN-GCPDS/qt-material.
