New display for Critical Edition Objects.

Now displays two tables.
One for paging though all the versions and manipulating them and their children.
One for paging though all the collations and manipulating their transcripts.

Manage tab's for versionable object's and critical editions such that we can
link to specific vertical tabs.

Now the module has soft dependancies on Views/cTools for display of links.
