[PATCH 2/2] Enable debug output to see what folderfilter actually filters out

[Sebastian Spaeth]

It is currently very hard to find out what folderfilter actually does
and makes it hard to debug for a user. With this patch if the user has
enabled "-d imap" (even better would perhaps be a different debug type
for this kind of thing?), we see a message
"Filtering out folder 'foo' due to folderfilter"
in the logs.
