Remove tests

Tests for Gnome Music were useful on early stages of development, but now they are:
 a) hard to maintain
 b) test only insignificant minimum if functionality
 c) quite useless without CI or constant control

Good night, sweet prince
Only allow left-button click to trigger events

By design we don't want that {right,middle}-button click triggers
any kind of action in gnome-music.

Merge pull request #94 from roignac/master

view: escape titles in album view title
application: Destroy window on quit

The quit method calls Gio.Application's quit method, which is currently not
implemented by Gtk.Application. Destroy the main window for now.
Create new file mpris.py

The file will contain the service for all interfaces of MPRIS implemented
by gnome-music.
