handle bad cookies Roundup's cgi gets all cookies from all apps on the same server. some apps aren't as well behaved as roundup and generate cookies that do not follow the spec perfectly. This causes python's Cookie module to throw an exception when trying to parse them. In the spirit of being liberal in what we accept, we create a LiberalCookie class that can handle those out-of-spec cookies and allow roundup to continue onward. [SF#1691708] code from S. Woodside
