A helper function which provides a textual string conversion
of a particular Status column.
In a PackageRequest, Status is split up into four different types:
- PENDING : "Pending", PENDING_ID: 0
- CLOSED : "Closed", CLOSED_ID: 1
- ACCEPTED : "Accepted", ACCEPTED_ID: 2
- REJECTED : "Rejected", REJECTED_ID: 3
This commit adds constants for the textual strings and the
IDs. It also adds a PackageRequest.status_display() function which
grabs the proper display string for a particular Status ID.
