convert to SDK-style projects

It's a first step towards cross-platform. If you try a different framework on top (upgrade-assistant upgrade .\CompileScore.sln) it chokes on the WinForms stuff though.

My knowledge on C# configurations is quite limited tbh. Thanks for your help and contribution. Super appreciated!!

I checked the changes locally, and it looks like the Visual Extension projects are no longer generating the vsix files.

3>CompileScoreVS17 -> C:\Users\ramon\Documents\Code\See\CompileScore\CompileScore\VSIX17\bin\Debug\net472\CompileScore.dll
1>CompileScoreVS16 -> C:\Users\ramon\Documents\Code\See\CompileScore\CompileScore\VSIX16\bin\Debug\net472\CompileScore.dll

I reverted back the the CompileScoreVS16 and VS17 'csproj' so we are still generating the extensions.
