Log Message:
Update mail/isync to 1.0.2
- remove patch-af, as it is already in the release
- take maintainership.

Changelog:
* src/compat/main.c: fix 'isync -w' writing .mbsyncrc to a wrong directory
* src/sync.c: less confusing uid ranges in debug
* src/sync.c: - sanitize flag handling of expired messages
  - don't record we synced flags if we didn't
  - remove now superfluous temporary rflags
* src/drv_maildir.c: less confusing error message on invalid mailbox.
* src/drv_imap.c:
revert 1.8 - what was i smoking?! the CREATE argument is already quoted;
we just extracted it from the previous command. ( that was patch-af )
* src/drv_maildir.c:
  make flag changes unset "new" status - unless a ghost is acting in the
  background, a flag change indicates that the message was at least
  noticed.
