Added new feature Send references to F# Interactive

### Added new feature Send references to F# Interactive
The new feature collates the current project references and sends them to F# Interactive
This is achieved as follows:
* Project references are retrieved from IdeApp.Workbench.ActiveDocument.Project.References
* An MSBuild task called ResolveAssemblyReference is created to topologically sort the references
* The sorted reference are then sent to F# Interactive.
