Deprecate Lucene

.. use a simple free text search against the ridecache now we
   have all the texts available and in memory

.. no need to maintain an index, no dependency on a horrid lib
   with nasty dependencies and its faster too

.. the free text search is very simple, will need to bolster it
   over time e.g. it matches text not words
