Moved formatting from _views_send_prepare_mail() to
views_send_deliver(). This is more logical and avoids
saving (long) UTF-8 encoded addresses to varchar 255
columns in the database.

Earlier these events contained no data at all. Now you can get the
subject of the mail using getSubject(). More / all data from the
mail can be added if anyone actually uses this (and files a
request).

- Fix signature of EventDispatcherInterface::dispatch().
- Replace deprecated module_load_include().

Load node / user  data for token replacement if there is a nid / uid
field in the result row. Earlier data was only loaded if the base
table was nid or uid.

- mandrill renamed to mailchimp_transactional.
- Added phpmailer_smtp.
- Introduced constant VIEWS_SEND_MIMEMAIL_ATTACH_IN_MAIL
  to reduce code duplication.
