Hyperiond refactoring + preparation for ip restriction settings (#12)

* 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

* extensive refactoring of hyperiond
webserver: make client ip information availabel in request object - preparation for ip filters
proto/json server, use hyperion::getInstance instead of hyperion argument

* move creation of hyperion core into hyperionDeamon class
cleanup
