SendFunds now sending all options to Dwolla

SendTransactionOptions was updated some time ago to support the latest api from dwolla. The DwollaTransactionService was not updated to reflect these newly added properties. This commit fixes any issues related to sending funds with unintended consequences. Specifically, the funding source - which was causing all sorts of chaos for my project.
Created a new NuGet Package called DwollaApi.
Removed nuget dll's in lib and nuget package

removed newtonsof.json.dll and restsharp.dll from nuget package and from
lib folder. These should be installed when the NuGet package is added,
not be included in the package.
Merge pull request #2 from jasonatmoxy/master

Now sends all data passed into SendFunds method in the DwollaTransactionService.
