.NET API wrapper for the Skycoin node API

Expected Behavior

Access to the Skycoin node REST API implemented in .NET code or as a .NET assembly.

Right now this is only possible using code generated by SWIG , which requires memory handles

Generate with Swagger (share more info, please) . Beware of CSRF .

[x] Use Skycoin node Swagger spec to generate initial C# REST API client
[x] Add make target to automate generation in ./build
[x] Aforementioned target should copy / merge relevant files into source code tree
[x] README explaining the process
[x] Mention in CHANGELOG
[x] Patch the result Swagger-gen REST client to support specifying node address
[x] Update package metadata
[x] Run basic Swagger tests in Travis
[x] Unify testing code if multiple frameworks are used across source tree
