Copy parameters between views of the same type

We originally didn't copy parameters in GitilesView.Builder.copyFrom()
because parameters with meaning for one view type generally don't
apply to other view types (e.g. n/s parameters for log views). But
they do generally apply to the same view type, and we do want
parameters to stick around e.g. when navigating around similar log
views.
