NOTIFPLT-39 BYU contribution for student jobs datatables view with demo data

https://issues.jasig.org/browse/NOTIFPLT-39

Addition of a datatables-based view that presents available student jobs based on a user-implemented feed.
- studentJobs.jsp can be used as base to create generic datatables view (left to future project). Current page has aspects specific to BYU student jobs view (hiring centers, saved jobs)
- includes sample JSON file and date adjustments to always be relevant (for quickstart inclusion)
Hmmm... good catch.  Not sure why that is being removed.  I didn't see that in my IDE diff.
