Add in a minor currency like dollars and cents.

I really don't want Fe to end up being another iConomy.

I would imagine if it had 2 currency modes (with default settings, plus a minor currency of Au, since Fe is a scientific name for iron):

• 30.6 Fe
• 30 Fe 6 Au

There would have to be more possibilities too... so should currency be a Phrase-formatted message? Not sure.

I think I'm going to be keeping the default the way it is, so even after this commit it will still show up as 0.50 Fe or 4 Fe. I don't know if I'm going to have to edit phrases or not, I'll need to see.
