tidy up panel / modal mess

[elf-pavlik]

• panels - always visible (except when covered by modal)
  • status
  • control
• bars - show and hide + remember state for return from fullscreen
  • sidebar
  • mapcontrol
  • widgetbar
• misc - inside sidebar, show and hide + remember state for return from fullscreen
  • minimap
  • featurebox
• modals - only one visible at time
  • useroptions (preferences?)
  • featuredetails (view/edit[new])
  • overlaymanager
• submodal - independent from modal since not directly related to map interaction
  • widgetoptions

The function to remember the UI state was already implemented, now it is magically gone again. Anyone care to reimplement?
