Changelog for multiarg-0.2.0.0

Release 0.2.0.0, April 2, 2012 Changes since release 0.1.0.0: * Henceforth all public releases will have only even numbers in their release numbers (e.g. 0.2.0.0, 0.2.0.2, etc.) If a release has any odd numbers in its version, it is a development release. * QuickCheck tests are removed. Eventually I will reimplement these in a separate library package. * Added Feed function to System.Console.MultiArg.Prim; this allows you to carry out stateful parses without using a user state. Sometimes this aids in composability--for instance, I use it when combining parsers from different parts of the same program.
