Remove colors by really removing them from browser.xml, not marking them

2006-10-30  Martin Wehner  <martin.wehner@gmail.com>

	* src/nautilus-property-browser.c: (remove_color),
	(nautilus_property_browser_remove_element),
	(element_clicked_callback), (make_properties_from_xml_node):
	Remove colors by really removing them from browser.xml,
	not marking them deleted. That made it impossible to add
	another color with the same name later on.
	Also delete colors by their (unique) names and not their color
	values. That made it possible to delete built-in colors.
	Fixes #358893.

	Based on a patch from Emil Soleyman-Zomalan
