Bug in headerFull.jsp org.openmrs.headerFull.userBar extension point

In the org.openmrs.headerFull.userBar extension point on the headerFull.jsp page the extension url is used without prepending the request context path. The extension must then figure out the context path (without a current WebRequest context) which, while possible, is a pain. Other extension points start with the request context path and then add the extension url (see the org.openmrs.gutter.tools extension point in \webapp\src\main\webapp\WEB-INF\template\gutter.jsp) and, for consistency, this extension point should do the same.
