2003-05-05  Christian Persch  <chpe+gnomebugz@stud.uni-saarland.de>

 	* src/ephy-shell.c:
 	* src/ephy-shell.h: (ephy_shell_new_tab):

 	Implement the EPHY_NEW_TAB_APPEND_AFTER flag.

 	* src/ephy-window.c:
 	* src/ephy-window.h: (ephy_window_add_tab):

 	Changed parameter (gboolean) groupde to (gint) position, to support
 	specifying the position in the notebook to insert the new tab into.

 	* src/ephy-shell.c: (ephy_shell_new_window_cb):
 	* src/ephy-tab.c: (ephy_tab_new_window_cb):

 	Fix callers of ephy_window_add_tab for new parameter.

 	* src/ephy-notebook.c: (notebook_drag_data_received_cb),
 	(ephy_notebook_init), (ephy_notebook_insert_page):

 	Implement drag-and-drop of links to tabs.
