Handle CAPABILITY response in following cases:
1) When sent as part of the banner, no longer sends explicit
CAPABILITY command
2) When sent as an UNTAGGED response to LOGIN, updates stored
capabilities.
3) When sent as part of the TAGGED response to LOGIN, updates stored
capabilities.
Due to odd implementation of the CRAM-MD5 authentication, the
capability updates will not happen as part of the CRAM-MD5
authentication.
a) is already known if the server supports the NAMESPACE capability.
b) is included in the prefix anyway (=also known if namespace was set manually).
c) isn't needed when selecting a mailbox because we currently don't support folder hierarchy. So the delimeter is included in the folder name.

At cketti's suggestion, change the methodology for counting
server-side unread messages on an IMAP server from STATUS (UNSEEN) to
SEARCH UNSEEN NOT DELETED. STATUS (UNSEEN) does not ignore DELETED
but unexpunged messages and leads to incorrect results.

This variant only checks for unread messages in the last 300 messages
in the folder, so will be wrong if there are unread messages earlier
in the folder. However, it'll be more often correct than the old
version for the marjority of users.
Also, change the opening of folders for IMAP IDLE purposes to
read-only using EXAMINE instead of SELECT.
always-available select action. For the moment, this means
that widgets_on_left does nothing at all. based on feedback, I may kill
the preference and multi-mode behaviour entirely in favor of "show stars?"

Stars, "checkboxes" and color bars updated to actually fit in wide mode.

Make sure to close opened folders in finally blocks in
MessagingController.
Don't make another connection when deleting or copying a
message. (Nicely speeds up copy and delete, as well.)
Another connection is still created for creating a folder while
copying or deleting (a pretty rare event), and the IMAP IDLE
connections are not re-used for user initiated activity.
On each IMAP account, the expunge behavior can be set to expunge
messages in a folder as soon as a move or delete is performed on the
folder ("immediately"), each time the folder is polled, or only when
executed manually.
In the Message List, there is now an Expunge action in the option
menu.
In the Folder List, there is now an Expunge action in the context
menu (long-press on the folder).
For IMAP accounts, it is also possible to disable the copying of deleted messages to the
Trash folder, by setting the Trash folder to -NONE-.
Fixes Issue 536.
Separately, in WebDAV accounts, the user can now choose the
server-side equivalents of the special folders, just like for IMAP.
from SQLite at once. The hope is that this will improve perceived
performance on large folders by starting message display sooner.
In the case of a background sync while we're loading, we _may_ end up
doing more work than necessary, since we implement paging by "date
received"
