implement url scheme

If we want to go totally nuts and bolts, we could eventually design a qfriendslol url scheme. It should however be considered, if this makes things easier for anyone, or if it just complicates our simple application. In any case I don't think we should add urls into the user interface.

We might however support giving one from the command line. For example executing command...

qfriendslol qfriendslol://users/e4e8743ffd801b2a126de53607c9ccd383fb71b8/

...could open qfriendslol in the friend finder with a find launched on e4e8743ffd801b2a126de53607c9ccd383fb71b8
This would allow firefox to use qfriendslol as a helper application for qfriendslol-urls. However external helper applications are not widely used, and anyone using the application would probably just rather cut/paste the user id into the user interface.

It is also possible to have urls for the files. I see no use for such urls in our user interaface, but if someone wants to add qfriendslol support into wget she could go with something like...

wget qfriendslol://files/e4e8743ffd801b2a126de53607c9ccd383fb71b8/mugshot.jpeg

I repeat this is somewhat stupid, but I just had to write it down somewhere.
