Bug 13890 - Switch from full serials permission to 'routing' permission for reordering routing lists

For changing the sequence of patrons on a routing list by changing
one of the numbers via the pull downs, full serial permission is needed:

To test:
- Give your patron full serial permissions
- Create a subscription and a routing list for it
- Change the sequence on the routing list using the pull downs
- Verify this works
- Remove any of the serial sub permissions (claim serials or similar)
- Verify changing the sequence now results in a permission error
- Apply patch
- Verify that the permission error is gone now
- Remove the routing permission
- Verify the permission error is back (but this seems to make sense)

In general more fixes would be required to make all routing related
features depend on the routing permission, but I think this fixes
the bug making it depend on the correct permission.

Followed test plan. Works as expected.
