refactoring and cleanup (#2)
* make hyperion to singelton. remove arguments for config and hyperion - both are gettable via Hyperion::getInstance * refactor hyperiond * remove qt4 comapt make zeroconf mandatory refactor hyperiond * xbmcchecker is now a singleton * cleanup in hyperiond zeroconf switchable between static and shared linking * fix xbmcchecker
