Milestones for portal vaults
----------------------------

This example is from icecave.des, defined in the lua preludes:

{{
function ice_cave_milestone(e)
  crawl.mark_milestone("br.enter", "entered an Ice Cave.")
end
}}
The function is called from each of the destination map definitions:
: ice_cave_milestone(_G)
This marks down entering the portal vault in the milestones. When the portal
is entered, the destination map is chosen and the call to crawl.mark_milestone
is executed along with the rest of the map definition.
Adding milestones in a .des does have the slight catch of creating multiple
milestones if the map fails validation for some reason, so it's best used
in maps that will never fail validation.
