Rework main page UI

[jisensee]

The current approach will not scale well. New idea

• [ ] ~Show a selection of best/popular crews in a carousel~
• [x] Build a wizard-like flow to direct the user to the action action wizard
  • [x] User selects the service they want to use
  • [x] User selects asteroid they want to be on
  • [x] Filtered down by what crews are available for the selected service
  • [ ] Asteroids that the user can't use the service on (because no ships for example) are filtered out automatically => #23
  • [x] If only one asteroid would be a viable selection, redirects straight to the crew selection
  • [x] User sees a list of crews they can hire.
  • [ ] Sorting options for best bonus strength and price.
  • [x] Once a crew is selected, direct the user to the correct action wizard.
  • [x] If only one crew is available, redirect straight to the action wizard
