HQLPARSER-?? Fix detection of unconsumed tokens

QueryParser.getUnconsumedTokens() fails to detect unconsumed tokes if it's just one but works if there are multiple tokens.
HQLPARSER-24 Provide JPA to Lucene translation for 'order by' clause

* LuceneQueryParsingResult exposes now the Sort object corresponding to the 'order by' clause
* modify the grammar to trigger the appropriate methods in the delegate object when the sort criteria is reached
* The SingleEntityQueryRendererDelegate is responsible for handling the sort criteria and its specialised subclasses must build the Sort object for the target language
* make the LucenePropertyHelper available to LuceneQueryRendererDelegate to be able to determine the type of the property based on FieldBridge type
* public access for LucenePropertyHelper.getFieldBridge(  )
