[Seaside] Accessing the root component from a child one

Hi, I use this solution:

All my components have inst. variable identifying parent and I create every
component using parent: method.

Furthermore I probe root component recursively


            ^ (parent respondsTo: #root)

                                   ifTrue: [ parent root ]

                                   ifFalse: [ self ].

If one component wants to be root, it simply redefines the this method


             ^ self
