[PATCH 2/5] notmuch-new: Allow the tags of new messages to be manipulated.

[David Edmondson]

Add support for specifying a set of tags to be added/removed from
messages added to the database by 'notmuch new'. These tags are
addition to those specified in .notmuch-config. They can be used to
override the pre-configured tags (e.g. -inbox).
