Generate @JavaField in Swift for the public fields of a Java class

[DougGregor]

When generating Swift wrappers for Java classes (Java2Swift direction), we currently ignore the fields. Instead, we should generate @JavaField members so that fields can be accessed directly. For example, a Java class like this:

public class MyClass {
  public int value;
}

could be generated as:

@JavaClass("org.mine.MyClass")
struct MyClass {
  @JavaField
  var value: Int32
}

[DougGregor]

@jrosen081 Yes, that would be great!
