JAX-RS ResourceAssemblerSupport

This is just a copy of your ResourceAssemblerSupport.java in the mvc package.
I had to create a class like this to be able to use ResourceAssemblers with JAX-RS.
The essential difference between them is the static import of the link builder and, of course, the package.

There might be a way to use a single ResourceAssemblerSupport. That would be ideal.
