 * Fixed shifted text in the certificate trust panel.  The bolded title was never intended to show more than one line of text... the textview itself was shifting up  due to attempts to size it to fit in some situations, while the sheet was coming out fine.  We now use the informational text - a private method, used by iChat as well to set non-bolded informational text - for the detailed information.  This not only fixes #8702 but looks a ''ton'' better.
 * Use the independent window rather than the account sheet again.  I think the problem was the 0-pixel height of the content view the fake window was using; I've seen 0-sized windows act strangely before.  We now use a 1-pixel height, which looks just as good.
 * Set the security policy of the certificate panel to the SSL policy, since that's the Right One.  It has a description in the docs as "Basic X509 plus host name verification per RFC 2818" versus "Basic X509-style certificate evaluation" of the Apple Basic we were using before, for whatever that's worth.
