Fixes made while building NZ Marine Life

Hey Simon, 

These are the most important fixes that were made while building Auckland Museum's Marine Life app.

We did make a few other alterations such as a localization for Maori, and added Kingdom and Authority to the animal info - but these required changes to the core data model and classes, and as they were specific to our project I've left only the major bug fixes in this pull request. 

Cheers!
