Zuluru

Version 3.4 is now available. This version adds support for payment processing through Elavon, an option for "negative credits" (aka money owed by the player for some reason), and registration event grouping for organizations with large numbers of offerings. Also, all unit tests have been converted to use the "Fixture Factories" method, which speeds them up tremendously and simplifies addition of new tests in the future, all of which is great for ongoing development. And of course various minor bug fixes.
