[BUGFIX] Load all tours on start already

Tour may not start and throw an error instead:
    "startTour: SomeTourName tour not found"

This is because the tour is not loaded/initialized yet.

with this fix all available tours are always loaded.

* Pro: Tours working again.
* Con: Very negative perfomance impact (one request &
  data handling for each tour)
  → his fix should be  replaced again soon
