Facet filtering not working with multi-term facet labels

[Davis Marques]

Where a facet label has multiple terms (ex. "a long facet title"), filtering produces no results. The current controller implementation attempts to replace all space characters with an asterix to ensure that Solr interprets the facet label properly. However, it currently replaces only the first space and leaves the remainder.

FieldFacetController updated to replace all spaces in facet label with * char when building the query string.
