Store idle info in config file
Handle idle responses better
Loop multiple mail accounts for quota check
Lots of updates to IDLE mail sync
Fix parsing of occasional idle responses
Only let one thread per account have a timeout
Minor fixes
Large rewrites to imap sync script

I moved from imaplib to the stdlib version. I also fixed the problem
with terminating threads. I need to test it some more and I have a
couple of todo items to fix, but this should work much better.
