Rework FileSetIndexer and add text search

This commit will enable `all_text_tsimv` and `is_page_of_ssim` to be set
on the FileSet.  By adding `all_text_tsimv` to Solr, the OCR can be now
searched through UV and any hits will be highlighted.  In addition, if a
parent work has any child works that have the OCR, those hits will also
be indicated in the left pane via a blue magnifying glass.
