Updated GPE OOI Tool

- addresses JIRA item EPEDEV-396 - fixes geoJSON requested ERDDAP data for Safari - 
additional get parameters "page" and "itemsPerPage" caused an incomplete response. Safari  would not accept request.. we are still unsure why, but problem has been solved
- addresses JIRA item EPEDEV-397 for this tool (ticket remains open - updates will be completed on all mouseovers)
- code clean up
