* src/widgets/modest-mail-header-view.c:

* src/widgets/modest-mail-header-view.c:
        * Added modest_mail_header_view_update_is_sent. It detects
          if the mail is incoming or outcoming using the folder
          information.
* Added src/widgets/modest-attachments-view.[ch]:
        * New GtkTextView based view for attachments. It shows
          attachments as a list of links.
* src/widgets/modest-recpt-view.c:
        * Removed warnings that happened on instantiation of
          ModestRecptView. The problem was that a GtkScrolledWindow
          required to get adjustments in initialisation (even if they
          are NULL).
* src/widgets/modest-msg-view.c:
        * Modified to use the new ModestAttachmentsView widget, and
          removed old attachments_as_html as it's not required now.
* src/widgets/Makefile.am:
        * Included modest-attachments-view.[ch]
* src/Makefile.am:
        * Now gtk directory is gnome.
