Collective.eeafaceted.z3ctable

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

- In `VocabularyColumn` and `AbbrColumn`, store the vocabularies instances
under `_cached_vocab_instance` to avoid doing a lookup for each row.
This does speed rendering a lot.

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

- Fix Date column with SolR result
[mpeeters]
- Added `ExtendedCSSTable.table_id` and `ExtendedCSSTable.row_id_prefix` making
it possible to have a CSS id on the table and for each rows.
By default, we defined it for `FacetedTableView`, `table_id = 'faceted_table'`
and `row_id_prefix = 'row_'`.
[gbastien]
- For `ColorColumn`, do not redefine the `renderHeadCell` method but use the
`header` attribute as we return static content.
[gbastien]
- Added `BaseColumn.use_caching` attribute set to `True` by default that will
avoid recomputing a value if it was already computed for a previous row.
This needs to be managed by column and base `_get_cached_result` and
`_store_cached_result` are defined on `BaseColumn`.
Implementations are done for `DateColumn`, `VocabularyColumn` and `AbbrColumn`.

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

- In `faceted-table-items.pt`, group `<span>` displaying number of results or
no results under same `<div>` so it is easy to style.
[gbastien]

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

- Added `PrettyLinkWithAdditionalInfosColumn.ai_generate_css_class_fields`
attribute to make it possible to specify fields we want to generate a
CSS class for, depending on field name and value. This is useful for
applying custom CSS to a particular additional info field having a
specific value.
[gbastien]

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

- Added `BooleanColumn` based on the `I18nColumn` that displays `Yes` or `No`
depending on fact that value is `True` or `False`.
[gbastien]
- Added `PrettyLinkColumn` and `PrettyLinkWithAdditionalInfosColumn` columns
based on soft dependency to `imio.prettylink`.
[gbastien]
- Added `ActionsColumn` column based on soft dependency to `imio.actionspanel`.
[gbastien]
- Added `RelationPrettyLinkColumn` column displaying a relation as a
pretty link.
[gbastien]
- Moved overrides of `SequenceTable.renderRow` and `SequenceTable.renderCell`
relative to being able to define CSS classes by `<td>` tag and depending on
item value to a separated `ExtendedCSSTable class` so it can be reused by
other packages.
[gbastien]

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

- Make widget compatible with `eea.facetednavigation >= 10.0`.
This makes it no more compatible with older version.
[gbastien]
- Make package installable on both Plone4 and Plone5.
[gbastien]
- Reintegrated the `select_row` column from `collective.eeafaceted.batchactions`
as it is useable by other Faceted packages.
[gbastien]
- Reintegrated js variables view that manages `no selected elements` message.
