launchpadlib should implement __eq__ and __ne__

[Francis J. Lacoste]

Currently:

>>> launchpad.people['salgado'] == launchpad.people['salgado']
False

I think that should be True. We could probably implement __eq__ to look at the resource type URL and the object Etag and return True when they are equals.

For collection, we could probably return True whenever the identify URL is equals.

message:
  * launchpadlib/resource.py: Implemented __eq__ and __ne__ for Ressources,
    Collections and HostedFiles, with following rules:
     - two ressources are equal if the values of their 'self_link' and
       'http_etag' attributes are equal
     - two collections are equal if the value of their 'self_link' attributes
       are equal
     - two hosted files are equal if the values of their 'url' and
       'last_modified' attributes are equal
     - __ne__ always returns always the revers of __eq__
     - __eq__ always returns False if any error occurs

While fixing this is not an inherently high task, merging the community contributed branch is.
