Bug 294790 [KeyBindings] LegacyActionTools should support SWT.F13 - F20
bundles/org.eclipse.jface/src/org/eclipse/jface/action/LegacyActionTools.java
* 
	 * Support for localized modifiers is for backwards compatibility with 1.0.
	 * Use setAccelerator(int) to set accelerators programatically or the
	 * <code>accelerator</code> tag in action definitions in plugin.xml.
	 * 
	 * @param acceleratorText
	 *            the accelerator text localized to the current locale
	 * @return the SWT key code, or 0 if there is no accelerator
	 */
