:) Well, looking at clocks, it's not safe for me to rebase today :)

Anyway, I looked at the changes guys made and:
1, PortletCSS.init hasn't changed
2, code for minimizing portlet has changed, now it should be moved here: https://github.com/liferay/liferay-portal/blob/master/portal-web/docroot/html/js/liferay/portlet.js#L431,L440

(just in case you don't want to wait for me) :)
