DATASOLR-106 - Upgrade to Solr 4.6.0

Upgraded test configuration to match current release. Therefore the old
configuration had to be completely replaced in order to avoid conflicts
when starting embedded solr server.
DATASOLR-132 - Add support for Solr functions

`Function` can be used inside `Criteria` or `CalculatedField` to trigger
Solr built in function parameter execution.

`Critiera.where(QueryFunction.query("name:spring*))`
DATASOLR-133 - fix partial update for empty collection

If an empty collection is used as update value for a multivalued field
within a partial update, Solr erases all values except the id within the
document. To bypass this issue empty collections are convertet into null
values, whichs behaviour is correct by only removing values from given
field.
DATASOLR-132 - fix cyclic package dependency
DATASOLR-134 - update documentation on per field facets

Per field facets can by adding FieldWithFacetParameters to FacetOptions.
Though this feature was not documented within reference manual. Added an
example to the facet section.
DATASOLR-104 - Enable multicore support via configuration

Via the multicoreSupport attribute within EnableSolrRepositories it is
now possible to bootstrap multiple repositores with different templates
dynamically created for the registered  types. 

Please note that multicore support will only work if the domain types
are properly annotated with SolrDocument providing required
core/collection information.
