Update to 1.0.2:

Fixes several bugs. This release also adds compatibility with upcoming
Dovecot v1.1 so it'll be possible to upgrade to v1.1 and back to v1.0.2
without anything breaking.

	* dbox isn't built anymore by default. It will be redesigned so it
	  shouldn't be used.

	+ Maildir: Support reading dovecot-uidlist (v3) files created by
	  Dovecot v1.1.
	- Maildir: "UIDVALIDITY changed" errors could happen with newly
	  created mailboxes
	- If "INBOX." namespace was used, LIST returned it with \HasNoChildren
	  which caused some clients not to show any other mailboxes.
	- Maildir++ quota: If multiple processes were updating maildirsize
	  at the same time, we failed with "Unknown error".
	- IMAP: IDLE didn't actually disconnect client after 30 minutes of
	  inactivity.
	- LDAP passdb/userdb was leaking memory
	- deliver: %variables in plugin {} weren't expanded
	- deliver: Don't bounce the mail if Sieve plugin returns failure
