Update data/params after Bugzilla 4.2.11 upgrade

Update data/params after Bugzilla 4.2.11 upgrade

* data/params:
(default_search_limit): Bump up the default search limit from
500 to 1000 because Timothy Horton asked nicely.
(maxattachmentsize): Make it an even 20 MB.
(maxlocalattachment): Bump up total amount of local attachments
stored on disk from 10 MB to 1 GB.
(smtp_debug): Let Bugzilla have its way with the config file.
(smtpserver): Fixed to use the correct mail server.
(sslbase): Fix test value that I checked in when I was testing
the update.  This caused bug mail to be sent with a URL of
bugs-test.webkit.org instead of bugs.webkit.org until around
11:45 AM PDT on Thursday, October 16, 2014.
(urlbase): Ditto.
