Lots of changes. Made a currency object so that all govs of a
commonEconomy have one currency object. This will make synchronization
inherent, which is the idea of this rewrite. I tried to get the bukkit
developer who built the convo API to change it so that if
blocksForInput() returns false, the convo returns the output of
getNextPrompt(), but no go, so I just added a line that allows for
acceptInput() to call  getNextPrompt() if input arg is null. Added a
military level field to Subjects.java. The military level of any gov
that does not have subjects is the same as the military level of it's
superGov. Expanded the newGov Prompt Chain so that it now gets the name
of money and the Money Multiplyer
