webmail: when moving a single message out of/to the inbox, ask if user wants to create a rule to automatically do that server-side for future deliveries

Browse Source 
if the message has a list-id header, we assume this is a (mailing) list
message, and we require a dkim/spf-verified domain (we prefer the shortest that
is a suffix of the list-id value). the rule we would add will mark such
messages as from a mailing list, changing filtering rules on incoming messages
(not enforcing dmarc policies). messages will be matched on list-id header and
will only match if they have the same dkim/spf-verified domain.

if the message doesn't have a list-id header, we'll ask to match based on
"message from" address.

we don't ask the user in several cases:
- if the destination/source mailbox is a special-use mailbox (e.g.
  trash,archive,sent,junk; inbox isn't included)
- if the rule already exist (no point in adding it again).
- if the user said "no, not for this list-id/from-address" in the past.
- if the user said "no, not for messages moved to this mailbox" in the past.

we'll add the rule if the message was moved out of the inbox.
if the message was moved to the inbox, we check if there is a matching rule
that we can remove.

we now remember the "no" answers (for list-id, msg-from-addr and mailbox) in
the account database.

to implement the msgfrom rules, this adds support to rulesets for matching on
message "from" address. before, we could match on smtp from address (and other
fields). rulesets now also have a field for comments. webmail adds a note that
it created the rule, with the date.

manual editing of the rulesets is still in the webaccount page. this webmail
functionality is just a convenient way to add/remove common rules.

- todo: buttons/mechanism to operate on all messages in a mailbox/search query, without having to list and select all messages. e.g. clearing flags/labels.
- todo: can we detect if browser supports proper CSP? if not, refuse to load html messages?
- todo: more search criteria? Date header field (instead of time received), text vs html (only, either or both), attachment filenames and sizes
- todo: integrate more of the account page into webmail? importing/exporting messages, configuring delivery rules (possibly with sieve). for messages moved out of inbox to non-special-use mailbox, show button that helps make an automatic rule to move such messages again (e.g. based on message From address, message From domain or List-ID header).
- todo: integrate more of the account page into webmail? importing/exporting messages, configuring delivery rules (possibly with sieve).
- todo: configurable keyboard shortcuts? we use strings like "ctrl p" which we already generate and match on, add a mapping from command name to cmd* functions, and have a map of keys to command names. the commands for up/down with shift/ctrl modifiers may need special attention.
- todo: nicer address input fields like other mail clients do. with tab to autocomplete and turn input into a box and delete removing of the entire address.
- todo: consider composing messages with bcc headers that are kept as message Bcc headers, optionally with checkbox.
