[Chameleon] Can't use setcookie

[Abe Gillespie]

I'm not terribly familiar with cookies either.  I just know it's set
with the header information, therefore if the header has already been
sent (i.e. output to the client has already started) then the call to
setcookie fails.  You can't modify something that has already been
sent.  In short, you need to call setcookie before headers are sent.

I'll give it a look.  Thanks.
