* src/NetworkManagerAP.[ch]
		- (nm_ap_new_from_ap): copy original essid too
		- (nm_ap_unref): free original essid
		- (nm_ap_get_orig_essid): new function
		- (nm_ap_set_essid): Convert essid to UTF-8 for display and dbus,
			but keep original essid around too

	* src/nm-device-802-11-wireless.c
		- (supplicant_send_network_config): send wpa_supplicant the
			_original_ essid, and not as a string, but in hex.  Should
			allow us to connect to more APs that use wierd character
			encodings for their essids

	* utils/nm-utils.[ch]
		- (nm_utils_essid_to_utf8): make a best-effort to convert the essid
			to UTF-8.  If it's not already valid UTF-8, we check LANG and
			use the current locale as a hint for what encoding the essid
			might be in.  Obviously not 100% accurate, but the idea here is
			that if a user's locale is ex. ja_JP, they are more likely than
			not to be in Japan, where access points will likely be in some
			Japanese encoding.
