[SLING-3146] Out-of date "Discover Sling in 15 minutes"

Description

When following instructions from "Discover Sling in 15 minutes"
(http://sling.apache.org/documentation/getting-started/discover-sling-in-15-minutes.html),
the steps ask to download org.apache.sling.launchpad-6-standalone.jar,
and run it via java -jar ....
Indeed when running it, I stumble upon an AIOB exception,
which looks like the one described in SLING-2348.
However this bug should have been fixed in May, 2012,
and the jar seems to be from Jan, 2013.

I'm not sure whether:

• the link to the launchpad jar is the good one
• the apache mirrors are providing the good file
• or there has been a regression (in which case SLING-2348 should be reopened ?)

In any case, the first impression is disappointing

Thanks,
Eric
