Cleaned up Exchange Rate plugin: more efficient code and more intuitive names for the get fiat balance/price procedures. Created new procedure used for updating the fiat balance & price on the status panel. Enhancement: status panel on bottom left now shows the current BTC price (eg, 1 BTC~573.45 USD).
