Added query template support to the new JavaScript Search API.

Browse Source 
- JavaScript search query now supports adding query templates to the query definition object:

   search
   {
      query: string,
      store: string,
      language: string,
      templates: [],          optional, Array of query language template objects (see below) 
      sort: [],
      page: object
   }
   
   template
   {
      field: string,          mandatory, custom field name for the template
      template: string        mandatory, query template replacement for the template
   }

   see http://wiki.alfresco.com/wiki/Full_Text_Search_Query_Syntax#Templates
