Added style_set handler.

Fri May 22 03:02:40 1998  Owen Taylor  <otaylor@gtk.org>

	* gtk/gtkhandlebox.c: Added style_set handler.

Fri May 22 02:55:57 1998  Owen Taylor  <otaylor@gtk.org>
 [ From: Chris Lahey  <clahey@umich.edu> ]

	* gtk/gtkeditable.c, gtk/gtkeditable.h,
	  gtk/gtktext.c, gtk/gtkentry.c: Added get_position,
	  and set_position functions to get and set the cursor position.

        * gtk/gtkeditable.c: Restored "insert_text" and "delete_text" to
	  signal status. Make GtkText do user-controlled insertion
	  and deletion through the Editable widget so that these
	  signals are properly emitted.

	* gtk/gtkentry.c: Changed gtk_entry_set_visibility to
	  display asterisks instead of empty space when visible = FALSE)
