Quick fix ,so it can handle no solution in the folder
Adding missing unit test
Adding rename support for F# scripts
Update notes
Renamed ScriptResource to CSharpScript so it is better distinguished from
FSharpScripts.
Also fixed FileExt variable in FSharpScript and CSharpScript so that they're
assigned before OnLoaded is called, which is too late. They have to be set
at static constructor time.
Updated Duality references.
Refactoring to add fsharp project
