Metacat

add comment/pointer to BioPortal annotation service.

Include method to look up annotation classes from BioPortal. We still have OBOE-SBC in there, and theyhave the SWEET ontology. The suggestions returned are not perfect, but they can be better than nothing. Ideally, we'd only query a few ontologies so we don't end up using terms from medical ontologies that aren't really appropriate for our domain. https://projects.ecoinformatics.org/ecoinfo/issues/6256

Add xpointer FragmentSelectors to each annotation.
Split attribute label into tokens to attempt matching to OBOE concepts.

include code to generate random annotations for UI testing. Effective, but can be confusing to see so many unrelated concepts on duplicate EML packages.

include characteristic_sm field with SPARQL query

include SSLVerify* directives for client certificates and a pointer for getting the DataONE chain files.

Added an explanation of "metacat context" to the Metacat Themes docs based on questions asked by an actual user following our instructions in the docs.

Edited the docs to incude more details about creating a custom theme

Remove the code to lookup alias dn in the getGroups method.

Rather than directly to modify the env, we use context.addToEnv.
This fixed a bug in non-tls env, the alias log-in doesn't work.
