content views - add content view to changeset history
content views - update changesets content tree to retrieve repos from default view

This commit contains changes so that when a user is on the Changesets
page and they are navigating through the left Content tree the
repositories used are always based upon that environments default
content view.  This is necessary to ensure that packages, errata,
repos, distributions...etc that are views are not coming from
any published content views.  (Published views are currently
always based on content view definitions created by the admin.)
content views - update product.repos to handle default content view

Minor update to the product.repos so that when invoked, it will
return the repos that are associated with the default content
view.  Previously, it would return all repos (including those
that are contained in other published content views)
content views - spec fixes based on changes to support default content views

This commit contains a couple of minor changes needed after
changes were made so that each environment has a default
content view.
Content views: showing repo info in cli
Content views: worked on changeset deletion of views
content views - fix for specs failing in ruby 1.9.3

For ruby 1.9.3, need to explicitly list arguments.  In ruby 1.8.7,
the call where no arguments specified would succeed.
