	* ecore: time to cleanup ecore_con_url time.

	Patch by Patch by Raphael Kubo da Costa <kubo@profusion.mobi>

	As discussed on the development mailing list, we should accept a
	double instead of a time_t for consistency with the rest of the API.
	Some apidox has been added too, and as a result
	ECORE_CON_URL_TIME_LASTMOD has been removed, since it does not make
	much sense (it is an HTTP response header).
