[mpris] Compliance tester

[Alex Merry]

I just want to point people towards a compliance testing application 
I've been working on for media players implementing the MPRIS2 
specification.

It can be found at
https://github.com/randomguy3/mpristester/

It currently covers the root and Player interfaces, and is fairly 
thorough about the tests it performs.  It isn't an automated testing 
tool - testing the setting of properties and calling methods requires 
user interaction.  Currently, it doesn't check that the desired effect 
was had, but that's something I want to add.

It requires Qt - at least 4.5, and possibly 4.6.  It can be built with 
either qmake or cmake.

TrackList and Playlists support should follow at some point.

I've used it to fix Amarok's MPRIS2 support.  Hopefully other 
implementors will find it useful, too.  If you want to contribute to it, 
just let me know - I'd be happy to have help.
