add support for iso 19139 metadata.  fixed an issue with grabbing the
title from fgdc records, where if the title from lcitation block appears
first in the document, it is used instead.  added support for capturing
browse graphic urls and zip file urls in the location field.
check a second tag to see if a record is FGDC CGDSM (original tag
sometimes not populated).  fixed a bug in recognizing argis rest
services.
changed handling of keyword thesaurus requirements so that it can be
changed via the ui instead of hard-coded.  

updated dependencies.  

removed the logger post processor.

added ingest from WMS getCapabilities

added capability for incremental status responses, so http messages
don't get too big for large metadata batches.  Also changed status boxes
to fixed sizes with scroll bars.
save some dev work
