Add documentation elements to the grails.dsld file

The groovy-eclipse dsld language supports adding javadoc-like tags to contribution elements. You can add documentation inside of a contribution block like this:

currentType().accept {
   method name:"myMethod", ... doc: """
        Here is some documentation.  
        Some <b>standard</b> html tags are recognized."""

  property name:"myProp", ... doc: """
        properties also accept documentation"""
}

Please let me know if you need any help with constructing the documentation.

I don't think it is necessary to provide too much documentation. Just perhaps a sentence or two and a link to the documentation online.
