pep8 fixes
Merge branch 'testing'
remove old unread-related code completely
add config option: auto_remove_unread
implement autorm-unread

this reintroduces the automatic removal of 'unread' tag.
Instead of doing it when unfolding a message, it is now
done whenever the cursor us moved to a non-summary part
of the displayed message.

Also, it is dependant on the (new) config option 'auto_remove_unread'.
