Join forces with Briar GTK

Hey @fphemeral,

it's really nice to see another python client popping up! Thanks for working on it. I'm looking forward to play around with it!

When developing Briar GTK, I took care that I separated all the GTK code from the Briar headless wrapper code. You can see the separation at /src/briar/ as there exists a module for gtk and a module for api. What about if we combine forces and both use the same code for the api wrapper part?

We could create a new Git repository where I push that api wrapper part and where we work together on that part.
