Added more code into doRequest

I haven't done much last week on this project. I feel bad about that
and will be working on this more this week.  I feel that the code is
moving along in a positive direction. Once I get a basic version
together for what I think is right, I will work up tests. Anyone that
wants to do that now, feel free, but put them under the following
namespace:

com.popebp.bitcoin.exchange.btce.unittest
