* mail-config.glade: Split "Other" page into three pages, Display,
Composer, and PGP. Add HTML image stuff on the Display page and
default forward style on the Composer page.
* mail-config.c (mail_config_get_default_forward_style,
mail_config_set_default_forward_style): User-specified default
style for forwarding messages.
(config_read, mail_config_write_on_exit): Deal with forward style.
* mail-accounts.c: Handle HTML image display options and default
forward style.
* mail-callbacks.c (forward): New. Forward in the user-selected
default style.
(forward_inline, forward_quoted): Simplify these some. Remove the
fallback to forward attached when forwarding multiple messages: it
should just forward the multiple messages inline or quoted in
those cases. (Which it doesn't yet, but that's a bug.)
* folder-browser.c (context_menu): Remove "Forward inline" and
make "Forward" call forward() rather than forward_attached().
* folder-browser-factory.c: Update command/menu/toolbar/pixmap
gunk for the "MessageForwardAttached" vs "MessageForward" split.
* mail-session.c (mail_session_get_type):
* mail-format.c (format_mime_part):
* mail-account-gui.c (setup_service): Fix warnings.

camel_session_alert_user.
