Issue with Antlr4.Runtime.Standard vs Antlr4.Runtime

[Falthazar]

I was trying to get this working with a console project in Visual Studio.
I kept getting the following error:
'LanguageLexer.TokenNames': no suitable method found to override
Same error for the Parser and some other files.

After some digging I found out that the Antlr4 Language Support extension uses the "C# optimized" version of Antlr4, not the standard runtime. There are obviously a couple of differences, unfortunately.

Maybe add a switch to choose which runtime to use? Compiling GRunSharp with Antlr4.Runtime (vs Antlr4.Runtime.Standard) fixed the issue.
