bsn GoldParser .NET Engine Updated

[Arsène von Wyss]

I finished the support for EGT files, including groups, and bumped the engine version to 2.0. I hope I got the groups functionality as intended by Devin - the missing pseudocode left me with some guesswork.

In any case, the engine still reads and processes CGT files as well, and I kept the API compatible as well to make the transition to the new version smooth.

Devin, I also implemented a special EOF handling for blocks that do not consume their end token; the EOF is then "accepted" as end token as well. This makes sure that line comments work even if they are used on the last line of a file. I assume that this should also be OK for other blocks.

Happy coding, Arsène
