system - minor refactors for code that will be shared for system groups

This commit contains minor refactorings for some code that will be
shared for system groups.
system groups - initial commit to introduce group events

This initial commit contains some of the pieces needed to support
system group event history (e.g. nav/controller/model/view...etc).

There will be additional commits to complete this logic.  This
includes covering things like status polling from event history
pane, listing of systems on a given event (along w/ status)...etc.
UI Remodel - More updates to stylesheets to relfect changes in
converge-ui with regards to importing the proper scss files.
Adds font URL settings for compass to generate font-url's directly based
off the Relative Root Url.
Changes around using the user sessions layouts from converge-ui in order
to fit with new styling and to ensure consistent wiring of views to
controller.
removal of system_tasks, replace with polymorphic assoc on task_statuses

This commit removes the current system_tasks model and associations
between a system and task status.  It replaces it with a polymorphic
association on the task_status.  That association adds a 'task_owner'
to the task status, which any other model can be associated with (e.g. System).
This allows us to associate a task essentially with any other model
without requiring an additional join table (like the current
system_task).

Updated all existing code using system_task to use this new relationship.

Also, created a migration which will add the elements needed for
the relationship (task_owner_type, task_owner_id) to the model,
populate it with appropriate data based upon existing system_tasks
records and then drop the system_tasks.
Adds a rake task that explicitly specifies the directories to look in
for translations.  This was done to add in and address translations
living in the dependent converge-ui project.
Merge branch 'master' of github.com:Katello/katello into fork-group_events
Updates pathing for some assets in converge-ui and bumps the version to
include recent login and re-factor work.

system packages - fix event binding

The the unbind that was being done for the +Add and -Remove link
was not correctly unbinding the event.  As a result, it was
possible that multiple events would be generated when the user
clicked those links.  This commit addresses that issue.
system and group actions - replacing .spinner with use of image_tag

Currently using the .spinner on these views does not generated a desired
affect.  Essentially, a div is added causing spinner and status text
to be on separate lines.  For now, to avoid this, going to use the
image_tag direct.  If the issue w/ .spinner class is resolved, this
commit can be reverted.
task status - clean up some of the status messages
