.NET wrapper for snowcrash parser: https://github.com/apiaryio/snowcrash

This fork has been created with purpose of building it on AppVeyorn, autogenerate a nuget package and push it on the repository. Some modifications were necessary to fit my needs. Here is in particular what I have done and what I want to do.

• Change the submodule to use public repository URL
• Update the wrapper to the latest snowcrash version
• Change configuration for Release version of DLL (it does not compile, actually)
• Make it compile on AppVeyorn
• Find a way to make it AnyCPU compatible (side by side assembly loading, I think)
• Create a nuget package and autopush on it (x86 only for now)
• Can we do something to support Mono and Unix as well?
• Remove various warnings due to a lot of deprecated stuff.
• Run a code analisys on the entire project (removed disposable warnings)
• Full managed implementation ?!
