Error in displaying unspent gold value of value greater than 999

This may be a code bug.

When a character's unspent gold is greater than 999 (or less than -999), an error message is displayed in the console, and no value is printed on the preview character sheet. My guess is that it's being confused by the comma. I haven't checked this on other OSes.

Here is the error message:
06:55:52.23 SEVERE Character-Sheet-Refresher-Thread ExportHandler:2075 Error replacing GOLD.TRUNC
