Triple-quoted strings are marked as comments in the gherkin grammar file

[WorldEnd-Admin]

Triple quoted strings are used to pass additional data to steps. They should be marked as a type of string (string.quoted.triple maybe), not a comment, so that e.g. they can be styled to have a different color than actual comments (which start with a #)

I will add this to list for v0.7.0 and keep issue open until that release.
