Rails 4.1 upgrade
Skin finally updated; everything functioning

I completed the update of the skin with the present functionality.
I improved a few items with a skin update such as buttons as radio
buttons and a selector for the job in the audit trail details.
Improved search

Search now has a better regex that doesn't expect two characters
between search terms. I also implemented a "assume last name first"
functionality that can be set in the configuration variables as per
the zoho task.
Added select all for cart

The exams list now has a select all button. I also improved the
functionality of the individual select buttons so that they update
each others totals appropriately.
Audit filtering by job status

Added a filter for job status in the audit logs.
