[dev] Patch for extended search on imap search

[Dan Wilson]

My spam filter was matching to every email.  I'm not sure if this is the right
way to fix this problem, but it works.  I've attached a patch.

I think this is actually the improper fix.  With some debugging, I found that
the Spam filter (which keys off of X-Spam-Status) was appending the 'ALL'
search flag to the $ob->fullquery (line 174 or lib/IMAP/Search.php).  I have a
feeling that's not correct... but I'm not sure.
