Small changes to Nancy and Falcore test fix

I changed two files in the Nancy directory. Since the Nancy modules were moved into a new folder, I updated the `source_code` file to reflect that. In addition, the `libevent2` implementation of Nancy was pointing to the wrong root directory, so I fixed that as well. `Mono` and `libevent2` will run, but both will fail their tests. Nancy-Mono has an issue that can further be explored on Xamarin's bug tracker [here](https://bugzilla.xamarin.com/show_bug.cgi?id=20543). It involves that Nancy is located within a folder `C#`, and Mono has trouble referencing the folder because anything past the `#` character is dropped off. Our own error looks like this:

    System.Web.Compilation.CompilationException
    CS0006: Metadata file `/FrameworkBenchmarks/frameworks/C' could not be found

I was also able to fix the Falcore test suite. I moved pathing to a `bash_profile`, which helped solve `GOROOT` not being set properly. Also, `JSONResponse` no longer lived in the `falcore` package, but was moved to the `falcore/responder` package. This was causing the framework to not run at all (obviously the result of Go's weak implementation of package management). The tests are running and passing now.
the former, but be aware that args is the name of the argument passed into
setup.py's start method, so you cannot reference it until that method is
invoked. If you only need root unside of start(), just move the variables
there. If you need root inside of stop too, you need to say something like
`root = ''` in the module, then redefine it to `root = args.troot` inside
the start function
