[imp] Filter by Header

[Michael M Slusarz]

Quoting Michael M Slusarz <slusarz@bigworm.colorado.edu>:

| The plan is (was) to move all filtering code to a IMP_Filter class.  I
| will 
| eventually be getting around to this (I hope) but if someone wants to 
| start, that's fine.  I personally would prefer that no "patches" or
| "hacks" 
| be implemented since the filtering code will get pretty hairy very fast -
| any future work should be consolidated into a single location.

I created an IMP_Filter:: class in HEAD and moved the filtering code from 
mailbox.php to it; all future filtering code should go in here.  I will try 
to work on this as I can.
