Collective-eeafaceted-z3ctable

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

- Correct wrong release.
[gbastien]

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

- 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.
[gbastien]
- 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.

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

- Display the 'Refresh search results.' link also when there are no current results.
[gbastien]

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

- Add english translations.
[sgeulette]

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

- Made BrowserViewCallColumn more generic, use unrestrictedTraverse instead of getMultiAdapter
[sgeulette, gbastien]
- Added DxWidgetRenderColumn to render a dexterity field widget
[sgeulette]
- Added RelationTitleColumn to render a z3c.relationfield.relation.RelationValue attribute
[sgeulette]

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

- Splitted the 2 viewlet managers to be able to add viewlets above and below batch navigation,
henceforth we have 4 viewlet managers : 'collective.eeafaceted.z3ctable.topabovenav',
'collective.eeafaceted.z3ctable.topbelownav', 'collective.eeafaceted.z3ctable.bottomabovenav',
'collective.eeafaceted.z3ctable.bottombelownav'.
