Added loan-specific option for due date, and hold-specific option for time till pickup
Added confirmation dialog for creating a new hold/loan.
Typed in php code for processing code.

Defect: apparently in order to use $_POST you have to use the 'name' attribute. This conflicts with the tag I've been using to filter the hold/loan special info.  Will have to research this.
Adding functionality to insert holds.
Added script to modify hold table in db.
Fixed defect with insert query
Got insertion working, except for redirect back to source page.
Merge branch 'master' of https://github.com/sjdixon/CPSC471Library
