remove "main" timer for OnUpdate

remove some spaghetti code to use "main" timer.
Instead add timers to the objects which really need them.
Natural events should be used ideally.

- Ui::OnUpdate removed
- SpringLobbyApp m_timer removed
- Download tab has now its own 2s timer
- TASServer has own 100ms timer
- The autoconnect and first run functions are triggered through OnInit in springlobbyapp
- Refactored FirstRunWelcome to be called by Ui::OnInit
better name: GetServerStatus -> IsServerAvailible (bool)
remove unused code in ui.
