Upgrading $config->minupgradefrom to 1.1 due to failures during upgrade tests

Bug 1243525: I found that attempting to do a direct upgrade from 1.0 to 1.8 failed in the
"$oldversion < 2008091601" code block. It would appear this has to do with the
former "textbox" block being renamed, and the solution would require that
block to be processed before the main upgrade script. Since that would be somewhat
hard to do, and there presumably aren't that many 1.0 sites still around, I've
simply updated the minupgrade to 1.1.
