Modifications for proper archive creation.
Extended BioPortalClient code, handler and test.
Fixed NullPointerException due to localISATABFolder not being set up (test case was load previous local file and save to GS)
Added service provider (OLS or BioPortal) as a comment on the OntologyTerm, renamed method setOntologySourceAccession to setOntologyTermAccession, removed code that extracted everything before a ':' from the ontology term accession, removed method removeRedundantSearchResults from the OntologySelectionTool (wasn't eliminating duplicates if accession numbers were different for the same term, now we show the service provider).
Changes to OntologyTerm class - returning copy of comments map, modified compareTo method
Single constructor for OntolgyTerm, assay files save term accession (not the substring after ':' anymore), columns annotated with term accession (not purl anymore)
Configuration parser adds ontology sources, removed redundant method in OntologyManager, defined Strings for ontology service providers.
Minor refactoring.

 Shortened method in NewFolderWindow by extracting button creation code.
 Prevented null pointer when no mode is specified by defaulting to Mode.NORMAL.
