Add import highlighting of deprecated types and members when type used as qualifier

[eric-milles]

Given the following:

@Deprecated
class Outer {
  class Inner {
  }
  static def method() {
  }
  public static final String FIELD = null
}

Semantic highlighting for deprecation in imports should be (taken from Java Editor):

Currently only the imports with Outer as their ClassNode (return from getType()) are highlighted correctly. Static imports are not showing deprecation for members if the type is deprecated.
