Improve HS_ClientManager and fix issue

1.No longer operate HS_Client in homescreen.cpp,move to HS_ClientManager class.
2.In hs_client.cpp,afb_event_push return the count of clients that received the event,
  not push event result, in tap_shortcut/on_screen_message/on_screen_reply directly
  return zero.
