Add keyboard shortcuts

[adaxi]

Hi @anduchs,

Your extension was exactly what I needed. I decided to improve it and add a keyboard shortcut to toggle to the next available output source. Would you be interested in a PR?

I noticed that this project has not been maintained recently. Some interesting pull requests are left unanswered.

Would you be interested in transferring the ownership to someone? I am interested.

Also going to throw in a comment here that adding a copy-left license (#20) and transferring ownership might be a good idea. This is a great plugin!

I forked the repository since @anduchs has not shown any signs of life. The gnome extension guys transferred the ownership to me. I'll gladly have a look at issues and pull requests.

Sorry for not showing up...

Please go ahead and take over. I also told the gnome guys I'm ok with this...

Please also consider talking over audio-input-switcher...

First of all, thank you for your work.
I can take over audio-input-switcher as well, and make sure it is compatible with recent versions Gnome.
If at any time you decide that you want to take over the development of the plugins back, I am fine with the Gnome guys transferring it back to you.

@adaxi I'd be very please if you'd do so...
Thanks a lot...
