* src/compose.c
fix 2 warnings
* src/gtk/prefswindow.[ch]
* src/plugins/spamassassin/spamassassin_gtk.c
changed the call of the widget create function
for PrefsPages, because sometimes the widget
create function needs a widget that already has
been attached to a window (to create GDK pixmaps
for exmaple). So we simply pass the GtkWindow as
the second parameter now.
* src/main.c
* src/mainwindow.c
* src/prefs_toolbar.[ch]
rewrite Toolbar Preferences using the new
prefs window
