Adding *.db to .gitignore, removing Freedom.db

As a dynamically generated binary database file, this does not belong in
version control. If a particular version of it is needed, please
checkout the appropriate commit, import database_creation, and run
loadDatabase()
Adding functional data -> ORM mapper to database creator

Adding characters
Adding environs
Adding military units
Adding planets
Adding possessions
Adding races

For planets, changed loyalty to sloyalty, added subsequent aloyalty as
per data file

Renamed 'numEnvirons' to 'environs_num'
Updating races data file

Previously an asterisk represented the race could only combat
hand-to-hand, that is, firefight is false, and an empty string ""
represented otherwise (true). I replaced these respectively with 0 and
1. This saves the headache of having to specially deal with weird input
that needs to be casted to a boolean anyway.
Merge branch 'db_creation_redux' into development
