[jbosscache-dev] Cache.remove() return value

[Brian Stansberry]

Any reason Cache.remove(Fqn, Object) is a void return instead of the
prior value for the key?  That breaks compatibility with old code.
Node.remove(Object) and TreeCache.remove(Fqn, Object) both return the
old value so I suspect the void return from Cache wasn't intentional.
