Landed on HEAD: GtkTreeModelFilter and the completion code

[Kristian Rietveld <kris gtk org>]

I just landed GtkTreeModelFilter and the completion features on GTK+
HEAD. The biggest part of the commit was adding new files, however three
source files were patched (apart from patching the Makefiles, etc):

	- gtk/gtkentry.c
	- gtk/gtkentry.h
	- gtk/gtktreeviewcolumn.c


A test program (yay) and documentation will follow ASAP next week. (And
for those wondering, yes the ComboBox will land next week too).


have fun,
