[BZ 1069662] (JON3-16) Adapt JON UI title bar to common Red Hat L&F

MenuBar rewriten using patternfly and is styled using new dark style. Also
added dropdown submenus to our main menu (including hiding them when
permissions are not met). Submenus more or less copy our view structure.
Notifications appear as a small box (patternflied) on right bellow
fav+messagebox buttons.
include respond.js so IE8 understands media queries, small fix in menu divider html output
