Fix crashes found after Qt5 change

There were a few things that caused sysmgr to crash on startup:
- uninitialized pointer in DockModeMenuManager
- DockModeMenuManager::dockAppContainer() was called before the
  pointer it returns had been initialized
- static QFont initializations caused crashes in PageTabBar,
  LabeledButton, PixButton, Icon, HorizontalLabeledDivider
  and TextBox
