This includes a new price_precision config entry to set the amount of decimal places to allow on a shop sign (set to 2 by default). Thanks to @andrewkm for this idea. It also fixes an issue where a zero inside the decimal places was removed instead of it's end and also removes the point and zeros from prices that only have trailing zeros to avoid confusion (e.g. in languages that use the decimal point for thousands)
