More bugs with pop3 processing

[John Schulien <jms uic edu>]

A couple more bugs:

in src/save-restore.c:

        if ( port == NULL )
          libbalsa_mailbox_set_host (mailbox, field, atoi(port));
        else
          libbalsa_mailbox_set_host (mailbox, field, 110);

This should be:

        if ( port != NULL )

Next, the Spoolfile variable is still being wiped out. 
In libbalsa/libbalsa.c, I changed

         Spoolfile = inbox_path;

to

         Spoolfile = g_strdup (inbox_path);

and got balsa working enough to read my mail.

One of the things currently broken with pop3 is refreshing the
screen after checking mail.  I have to enter balsa, press the 
check button, then exit balsa and restart it in order to see
the new messages. 

I really like the ability to select text from the current
mail window!
