/** If true, some widgets might parse plain text between their tags differently. For example: 
 *
 *  * <label>First.
 *      Second.</label>
 * <label multiline=true>First.
 *      Second.</label>
 * 
 *
 * By default, labels are single-line, so first label's text would be "First.Second.". Thanks to multiline
 * property, second label's text would be "First.\nSecond.". This attribute expects a boolean. By default, it is mapped
 * to "multiline" attribute name. While the mechanism used is common for all widgets, note that it will work only for
 * labels, text buttons, image text buttons and text areas (might work on text fields, too: the new line char is
 * appended, but text fields do not seem to support it by default).
