* gladeui/glade-utils.c: Hijack the cntl-n accelerator too now.

	* plugins/gtk+/glade-column-types.c, plugins/gtk+/glade-model-data.c, plugins/gtk+/glade-store-editor.c:
	Enhanced model editing, now there is completion in type names, and column types are defined inline
	with no add or delete keys, model data can be edited and navigated without using the pointer either.
