Same with tech_exists, of course.

improvement_exists seems to depend on server options.  OTOH it would 
probably be just as easy to skip those items when loading the ruleset. 
So eventually improvement_exists can be removed as well.

The advantage of removing these is that you no longer have to remember 
to check them.
