Fix #94 - Prevent NPE if the user taps "Load More Arrivals" and there is a bad response from the server.
Fix #97 - Add AndroidStyle.xml code style template and apply this template to the project via Android Studio.  Update Readme and Contribution docs to reflect the new official style guide and template.
Fix #99 - Reformat plural strings that include the <xliff:g> tag so they are all on one line, to restore spaces prior to plural values in prompts.  Also add comments above these lines in case they are reformatted, as Android Studio currently appears to be formatting these incorrectly based on the code style template.
Fix dangling </string> XML tag.
Fix typo (missing parentheses), and reformat URL to include entire style guidelines title.
