Fedora:
- add jsoncpp
- remove libsrtp
- add libappindicator-gtk3
- add missing gnome-client dependencies (gtk3, clutter, etc)
- add 'patch' as Fedora 24 does not ship with it

Ubuntu/Debian:
- add jsoncpp
- remove libsrtp
- add libappindicator-gtk3
- synchronise as both currently have the same dependencies
