I experienced the following issues with cookies:

1. "Set-Cookie" not searched for in headers case-insensitively. Not sure what the RFCs say, but reality is reality and some servers send "set-cookie".

2. Some kind of confusion in the Response object code between 'cookies' and 'cookiesjar' led to cookies not being made available in resp.cookiesjar. (Found with resp = hurl.post(...)).

3. URL-encoding the ('+' and '=' characters in) a cookie value was causing problems with a server that was not expecting the value to be altered.

This patch fixes these, but I am not submitting it formally since I'm not sure how you want to clean up (2), and (3) is not a final solution either.
