Currency Symbol Issue

Hello
Until 1.4.1 version the plugin was working great for me. But not with the last update.

The currency of my site is ARS (Peso Argentino) and the payment gateway is MercadoPago.

I have it configured like this: http://awesomescreenshot.com/00e3rojvcb

You can see i created a symbol that its not the default. And i like that.
If i type the symbol the same way in the new version, the MercadoPago gateway tells me the currency must be ARS, USD, etc. and it doesn´t work until i change that.

Also if i use ARS and Peso Argentino in the new version, my theme dont show the $ symbol before the “0” in the shopping Cart. Dont know why.
Thing is i hope you try to update to a new version with the old options. If not i will have to use the older version instead.

So the new version should have 3 options for custom currencies.
They should be these:
1) Currency
2) Custom symbol
3) The custom name of the currency

I hope you can do it.
Thank you.
