[ingo] Using multiple servers with different backends

[Davide Bianchi]

We have the problem of having multiple servers (about an hundreds) with
different backends: some servers are using Sieve, some others have
vanilla procmail scripts. The problem seems that Ingo does not support
multiple backends, even when configured to use more than one the
comparison done when the backend is loaded is done agains the name of
the HTTP server and not of the server that is selected by the user.

I've modified the php script to load the correct backend depending on
the server selected.
