[Paraview] How to have QWidget change the "Accept" state when it changes

[Utkarsh Ayachit]

All you really need it call setModified() on the pqObjectPanel
subclass every time the selection changes. That will enable the apply
button. Then override "accept()" and "reset()" methods to update the
servermanager-property using the selection  or vice-versa
respectively.
