Is it worth to add support for Eclipse Code Formatter

[letientai299]

I love Intellij IDEA, except the part that it's not handle non-javadoc comments nicely. Some time we need that type of comment to explain why we wrote code like that. and not other way.
Beside that, this repo is not only about Android. And lots of people still prefer Eclipse or Netbeans for their java development. There are Eclipse Formmater plugins for Intellij and Netbeans. So, adding only one more xml file may help lots of people.

I plan to make a pull request for this. But I'm not sure if it worth doing that.
