Mutable Realm

[Dain Sundstrom]

We're planning on using JSecurity in some REST applications.  Most of  
JSecurity should work for us out-of-the-box with the exception that we  
need our basic realms (text and database) to be mutable at runtime, so  
we can provide simple user management functions for standalone  
environments.

I have been looking at the realm implementations and don't think it  
will be difficult to add support for runtime mutability of simple user- 
>role->permission mappings.  Is this something the project would be  
interested in as a contribution?
