Bug 1361288 - Remove vestigial reference to advancedLongDesc and hide advancedButton for SSLv3 erros. r=johannh

Unfortunately, we can't simply restore advancedLongDesc because it will change strings. I hid advancedButton instead. The advanced panel will have no useful information for SSLv3 errors anyway.
