popup tour always starts

[btbonval]

This is a little annoying: If I'm logged out, the popup tour always starts. Always. Every note. Every page. Every time.

There should be a session cookie which counts up to three and then no longer displays the popup tour. It should be written so that if the counter is not there, set it to 1. if the counter exists and is in 1..3, then display popup tour and increment. This way if someone's cookies are disabled, counter is not present and popup tour does not begin at all.
