Changed the EDropdownButton so that it works more like a standard menu
bar (i.e. the menu is popped up on button_press instead of button_release). Now it is also based on GtkToggleButton, so it stays pushed down when the menu is on the screen. svn path=/trunk/; revision=7869

+
+ * e-dropdown-button.c (menu_deactivate_cb): New function to change
+ the state of the toggle button when the pop-up menu disappears.
+ (impl_clicked): Removed.
+ (impl_button_press_event): New, implementation for
+ `::button_press_event'. Pop-up the menu, and toggle the button.
+ (class_init): Override `::button_press_event' with
+ `impl_button_press_event'; don't override `::clicked' anymore.
+
+ * e-dropdown-button.h, e-dropdown-button.c: Derive from
+ `GtkToggleButton', instead of plain `GtkButton'.
