(svn r724) Remove restriction that a tile can only accept 3 cargo types.
This especially enables houses to accept passengers, mail, goods AND food.
Add string templates for up to 5 cargo types for the tile info window. If more are needed just add them.
Simplify (de-uglify) the logic for cargo acceptence for houses and split the goods/food table into two. The acceptance is unmodified, but accepting goods AND food is now trivially possible. The exact amounts have to be decided.
This is based on Celestar's changes in the map branch plus some further bits that will be merged there soon.
