* Source/x11/XGServerWindow.m (screenList): join RandR and non-RandR

Browse source 
code. Failback to Xlib generic method if any no RandR available or
  RandR function call was unsuccessful. In Xlib generic method fill in
  monitors array with values.
  (boundsForScreen:): use values from cached `monitors` array since
  -screenList fills it on both cases with or without RandR available.
