AbstractTransformer: renamed Util.isIdentifiableObject to isBasic
ClassTransformer: renamed Void to Anything
CeylonModelLoader: reverted patch that tried foo_ before foo

because it just didn't work for Java types that start with a lower-case letter
CeylonModuleRunner: rewrote to not invoke the typechecker twice

since the second time it didn't see the Java classes and failed with many errors
Fixed a bunch more tests
