* Radically culled the list of BApplication friends and introduced a

BApplication::Private class for accessing relevant parts.
* Pulled the app server connection and IK initialization out of
  InitData() into a new method _InitGUIContext() and introduced a private
  constructor that allows to avoid this initialization. This will be used
  for servers that don't have GUI respectively want to init the app server
  connection later.
