Title: Fix csv parameters

I needed to use the (undocumented) 'encoding' and 'dialect' csv parameters and they both yeld a "Data transformation failed. Reason: lookup() argument 1 must be string, not instance" error.
You can [see the error from the live jsonpdataproxy demo](http://jsonpdataproxy.appspot.com/?type=csv&format=jsonp&url=http%3A%2F%2Fdata.a2gov.org%2Ffeeds%2FFinance%2FPurchase%2520Card%2520Transactions.csv&max-results=50&encoding=utf-8).

The fix was quite simple.
I've also documented those parameters in the README.rst.
