Add support for templates without replacements in jqueryMsg

The template parser in jqueryMsg expect a replacement after the templatename as per the syntax

templateContents
  = twr:templateWithReplacement p:templateParam* { return twr.concat(p) }
   / t:templateName p:templateParam* { return p.length ? [ t, p ] : [ t ] }

templateWithReplacement
  = t:templateName ":" r:replacement { return [ t, r ] }

replacement
  = '$' digits:digits { return [ 'REPLACE', parseInt( digits, 10 ) - 1 ] }

This fails for {{GRAMMAR:genitive|{{SITENAME}}}} since genitive is not a replacement or not starting with a $. (grammar is yet to be supported by the parser.)

Attached patch resolves this by adding an option to templateContents like this:

templateContents
  = twr:templateWithReplacement p:templateParam* { return twr.concat(p) }
  / twr:templateWithOutReplacement p:templateParam* { return twr.concat(p) }
  / t:templateName p:templateParam* { return p.length ? [ t, p ] : [ t ] }

(Did not commit this code and keeping patch here since core code is in 'slush' )
