Bug 14697: Enhance the return claims feature

This adds a "Claims returned" feature that extends and enhances the claims returned lost status.
To use this feature, a new LOST status to represent an item claimed as returned needs to be created.
The value of this LOST authorised value should be set in the new syspref ClaimReturnedLostValue.
Setting this system preference turns on the feature.

Once the feature is enabled, you should be able to mark checked out items as return claims from the
checkout and patron details pages, and also modify them from the new claims tab on those pages.

Returning a claimed item will notify the librarian that the item in question has a claim on it.

Setting the ClaimReturnedWarningThreshold will add an alert to make librarians aware that this
patron has many return claims on the patron's record.

Test Plan:
1) Create a "Claims Returned" lost value
2) Create some RETURN_CLAIM_RESOLUTION authorized values
3) Set ClaimReturnedLostValue
4) Set ClaimReturnedChargeFee
5) Set ClaimReturnedWarningThreshold
6) Create some checkouts
7) Claim some returns
8) Verify ClaimReturnedChargeFee works with all 3 options
9) Verify ClaimReturnedWarningThreshold shows a warning once the threshold has been exceeded
10) Edit notes on a claim
11) Resolve a claim
12) Delete a claim
