	 * <p>Loads a properties file from the classpath</p>
	 * <p>Will parse a properties file found in the classpath.
	 * The file must respect standard properties conventions :
	 * <li>Name must end with .properties</li>
	 * <li>File content should be lines containing pair of key = value
	 * e.g : foo.bar = 42 </li></p>
	 * <p>For ease of use, the loader is flexible with the <i>name</i>
	 * of the properties file, and therefore :
	 * <li><i>name</i> can be described using <b>.</b> or <b>/</b> as separators</li>
	 * <li><i>name</i> can optionally end with <b>.properties</b></ki>
	 * <li>leading <b>/</b> in <i>name</i> will be ignored
	 * Therefore all the following <i>names</i> are the same :
	 * <pre>
	 * foo.bar
	 * foo.bar.properties
	 * foo/bar
	 * foo/bar.properties
	 * /foo/bar
	 * /foo/bar.properties
	 * </pre>
	 * </p>
	 * @param name classpath resource name
	 * @return resource converted to java.util.Properties
	 * @throws IOException when <i>name</i> doesn't describe a valid properties
	 * file
	 * @throws IllegalArgumentException when <i>name</i> is null
