fixed & simplified groovy step snippets

[hauner]

the generated groovy snippets do not work out of the box:

When(~"^I run cucumber$") { -> ... }

Error: Indentifier or code block expected, String end expected

the $ is a special character in groovy to embed an expression into a GString, ie. a double quoted string. To disable the groovy $ it has to be escaped...

When(~"^I run cucumber\$") { -> ... }

... or the string has to be quoted with single ticks (to make it a normal String) ...

When(~'^I run cucumber$') { -> ... }

Which has the advantage that the " does not have to be escaped as well. So it is possible to simplify

When(~"^I run cucumber with \"([^\"]*)\"\$") { String arg -> }

to:

When(~'^I run cucumber with "([^"]*)"$') { String arg -> }

I think everyone agrees that this is a lot better.. :-)
