Refactored .NET Core solution

- defined common props in Directory.Build.props
- removed dependancy on .NET Framework and MSBuild Community Tasks and replaced git versioning tasks with a powershell script.
- locked .net core to stable release in global.json to avoid a bug with FSharp project SDK not being able to parse a nuget version
- Reinstalled stylecop project reference into all projects
- renabled deterministic builds on FSharp projects by chaning output type to PDB
- Disabled short name tests because I could not determine any valid test or faulting case that still occurs (see #241)
- Removed vagrant file - soon will not be necessary
