Added new function islandora_copy_object() can copy existing/new fedora objects.

It's a bit leaky in that it makes assumptions about the members that will exist
on AbstractObjects, but we can't make cloning work at the moment as it doesn't
really work well with inheritance, every decendent would have to define __clone
functions properly and I figured a wrapper function like this would be easier
to support in the long term, until we make the movement to decorated objects.
Include an autocomplete path for content models that used to live in islandora_xml_forms.

Integration tests for ingest steps plus some fixes.

Tests ingest forms by using a shared variable 'models'.

Additional stuff:

'models' is no longer a required config for ingest steps, now
its set from the given objects.

No longer need to rebuild steps from within a form step when the
shared_storage gets changed, we now detect if changes have been
made then we rebuild if necessary.

Fixed POST requests in WebTestCases previously the user was always
anonymous so interactions with fedora would fail via post requests.
