*neutrino subchannel_menu: own modul for subchannel menu and clean up keyhelper class

- move keyhelper class into new file user_menue.h
  This class is made to manage only colorkeys, but has the same name like
  CKeyHelper in file keyhelper.h. This class is managing the other keys and
  it could easily lead to confusion.

- add modul subchannel/director menu, removed unused functions
  The subchannel_select.cpp/h modul contains the getNVODMenu() member, moved from neutrino_menue.cpp
  into its own class.
  Also removed member SelectAPID() and SelectNVOD()from neutrino.cpp this
  members were unused.
