Fix type inferencing and syntax highlighting for super trait method and property references

[eric-milles]

Consider the following:

trait Auditable {
  String option
  void audit() {
    if (checkCondition()) {
      println 'audited'
    }
  }
  private static boolean checkCondition() {
    println 'condition checked'
    true
  }
}

trait Another {
  private static boolean checkCondition() {
    false
  }
}

class C implements Auditable, Another {
  void m() {
    Another.super.checkCondition()
    Auditable.super.checkCondition()
    Auditable.super.option = 'whatever'
  }
}

Syntax coloring within the method m() should be "trait" for each occurrence of Another and Auditable. And coloring should be "method" for option, which refers to the property setter method. Code select for the sub-expressions in Auditable.super.option is not working either.
