Seaside components within Pier, and their state.

[Lukas Renggli]

I've committed Pier-Seaside-lr.445 that is supposed to fix the issue
with the state (as well as some other minor problems with cookies and
restful URLs):

  - fixes issue  where components lost state when PRRestfulSession was
used (http://code.google.com/p/pier/issues/detail?id=110)
