Comparing ImmutableObjects yields unexpected results

[tkem]

mopidy.models.ImmutableObject has __eq__ and __ne__ methods, but they sometimes yield unexpected results:

For example, I expected the following to all yield True, since the respective attributes compare equal:

from mopidy.models import Track
Track(name='foo', album=None) == Track(name='foo')
Track(name='foo', album=None) == Track(name='foo', album=None, track_no=0)
Track(name='foo', album=None) == Track(name='bar', album=None).copy(name='foo')

May I suggest this for the v0.19.5 milestone? Writing backend unit tests would be much more fun with this...

Done :-)

A small step for a man...
