	* app/actions/channels-commands.c
	* app/actions/vectors-commands.c: removed massive code duplication
	by factoring out the code that creates the "New Channel/Path" and
	"Edit Channel/Path Attributes" dialogs out to utility functions.
	GUI spacing and Code cleanup.

	* app/actions/layers-commands.c: minor GUI spacing and code
	cleanup.
