Support "javax.annotation.concurrent.Immutable" for immutability checks

I have a lot of code here, that uses "javax.annotation.concurrent.Immutable" to annotate classes that are - you may have guessed it - immutable.

Unfortunatley error-prone-compiler doesn't seem to recognize those annotations.

I'd love to see support for "javax.annotation.concurrent.Immutable". And maybe support all annotations that are called "Immutable". Independent from the package they are located in...
