Visual Studio plugin for Syntax Highlighting

[furesoft]

add editor with syntax highlighting and intellisense

or/and Visual Studio Plugin to compile ebnf file before build

[ed-cooper]

Compiling EBNF before build can already be achieved in Visual Studio by going to the Build Events menu in the settings of your project and adding a pre-build command to run Ebnf.Compiler.exe with the inputs given as command line arguments. (See the documentation for details of the arguments)

Syntax highlighting and auto-complete are both nice suggestions however and I'd be happy to review PRs for it.
