Merge Kilauea and Vesuvius Trunks

by Kaushika Rukshan Athukorala for Sahana Software Foundation

Full merging of Vesuvius and Kilauea code bases into single trunk. Deployment settings (like Eden) will determine front-end functionality (missing persons, shelter registration, staff registration, etc.). This would greatly broaden the potential user base for both of these products, which otherwise will remain highly customized for a single customer and likely not adopted by other organizations.
