Delayed expunge / undeleting messages

[Wesley Craig]

A bunch of people already pointed out unexpunge, so I'll point out  
that the delayed expunge / unexpunge functionality doesn't help if  
the user deletes a whole folder.  See:

	https://bugzilla.andrew.cmu.edu/show_bug.cgi?id=2871

for the problem report and a patch for a proposed solution.
