Tour

Hey @davidtlee, wanted to run this by you to make sure I'm not headed down the wrong track.

This implements tour on the home page. Have done 1-3 below, but not done the sub bullet points. Am I correct in understanding that we should also have a tour for the events#show page? Or just the home page? (The actions appear on the home page only, right?)

1) Going to the event page for basic FAQ/info
2) Navigating to your home page (where the actions are)
3) Completing an action

Is it possible to have this walkthrough trigger for the actual Finland event? i.e.
If a user creates an account through the "mass invite" functionality, then have the walkthrough trigger for the event that they were invited to.
Otherwise, if the user created their account by "signing up" on the website (not through a mass invite), then create a "Demo" event and action to use for the walkthrough.
