Multiple sort options for forwarders

I suggest that there be options for how Forwarders are sorted, as per:

a) Full source account@domain (current)

b) Source domain, then account

c) Full target account@domain

d) Target domain, then account.

These would make it easier to check that multiple entries are set up correctly, especially when managing multiple domains.

For example, we have a half dozen domains with 40+ forwarders that bounce to just three real accounts or black holes. It gets tedious to set up a domain when having to go though multiple pages because they are not sorted by domain.
