          addresses to the ModestRecptEditor instead of returning them.
* src/maemo/modest-address-book.c:
        * Implementation of the new ..._select_addresses method. This
          uses the osso abook api to retrieve addresses from device
          addressbook.

        * Added new add_recipients method, that adds a non resolved
          recipient to the recipient list.

          resolved recipients with an ID. It adds them underlined, and
          with a specific tag id.
        * Now recipient adders add the recipients one per line, adding
          \n. It also returns the recipients with the \n characters
          filtered.
        * Now it uses the ModestScrollText to support scroll line by
          line limited to 5 lines.
* src/widgets/modest-scroll-text.c:
        * Fixed a bug, that moved the cursor to the start every time
          the embedded text view changed its contents.
        * Correct the size request to take into account the shadow of
          the scroll.
* src/widgets/modest-attachments-view.[ch]:
        * Refactored to create a new add_attachment method. It's used
          to add new attachments to the list one by one, and in the
          existing modest_attachments_view_set_message.
* src/maemo/modest-msg-edit-window.c:
        * Added handler for "open-addressbook" signal in To: recipients

          mail priority, priority icon to the left of the subject,
          and sending mails with the priority field).

          functionality yet.
        * Added frame to the body editor.
        * Use HildonScrollArea to implement full view scroll.

          field.

        * Added minor fixes to avoid warnings (GSList method called

        * Now ..._send_new_mail method receives also the required
          priority for the mail.
