SHOULDERS update & grift task

[paganotoni]

@markbates i noticed the SHOULDERS doc still list raymond and given there is a commit that says it has been changed to mention velvet instead i was going to send a PR by running the shoulders grift but when i try to do it the grift task seems to be dependent on your personal repo

f, err := os.Create(path.Join(os.Getenv("GOPATH"), "src", "github.com", "markbates", "buffalo", "SHOULDERS.md"))

should i send a PR moving this to be

f, err := os.Create(path.Join(os.Getenv("GOPATH"), "src", "github.com", "gobuffalo", "buffalo", "SHOULDERS.md"))

and running the shoulders task to update the shoulders doc ? thoughts?

D'oh! Yeah, that should be switched to "gobuffalo" not "mark bates".

Raymond is stilled being used for its parser lexer in velvet.
