NPE in the sorter of the EnhancedRepeater

                 Key: COCOON-2035
             Project: Cocoon
          Issue Type: Bug
          Components: Blocks: Forms
    Affects Versions: 2.2-dev (Current SVN)
            Reporter: Gustavo N. Fernandes
         Attachments: SorterNullFix.patch

Steps to reproduce

1. Execute the enhanced repeater sample at http://localhost:8888/blocks/cocoon-forms-sample/pagination/
2. Click "Sort-by-name"
3. Click "Add player"
4. Click again "Add player"
5. Boom!

The sorter shipped wih EnhancedRepeater does not deals with situations where the value of
the field being compared is null

Suggestion proposed
A new parameter nullsAreHigh (default=false) are passed to RepeaterJXPathSorter that will
check for nulls and will sort based on the 
parameter. NullsAreHigh=false means that nulls are lower than anything else.
