[Seaside] body attributes?

[Andreas Nilsson]

Thanks, I totally missed the possibility of setting onLoad from within 
the script (Javascript is clearly not my thing), I'll try that instead.
Kind of suspected that the reason for the 'I call you' layout of 
updateRoot: was meant to allow for it to be called whenever Seaside 
feels like it.
