Static method calls

[miho]

Currently, static method calls are only possible if the invocation and the method definition are inside of the same compilation unit:

class A {
  public static void staticMethod() {}
  public void method() {
    staticMethod();
  }
}

Invocations like Math.abs(a-b) are not possible since the Groovy AST visitor assumes a non-static method invocation. But that can actually be resolved by checking whether the ObjectExpression is a class.
