Issue #49 added support for BASIC authentication. Default will still be Keystone. BASIC authentication can be set by calling setAuthenticationMethod(AuthenticationMethod.BASIC) on the configuration object.
Ascertain continuing Java 6 support. Lowered Maven Cobertura plugin to 2.5.2 (2.6 is Java 7). Used Unicode (\u instead of character itself) in Strings, removed Java 7 Diamond notations.
