among elements displayed in the table. This supports table using batch or not.

- Correct wrong release.

-----------------

- ColorColumn : in renderHeadCell, do not return an empty HTML content but `u'   '`
so in case table is too large, the column does not shrink to nothing.

- Use `__name__` instead of `attrName` to generate `th_header_` and `td_cell_` CSS classes
so 2 columns using the same `attrName` get different CSS classes.
[gbastien]
- Added `AbbrColumn` that will generate a HTML tag `<abbr>` and that is based on 2 vocabularies,
one that manage the abbreviated value and one that manage the full value.
