Fix print.tpl to include new regions CRM-12122

(not sure if these comments belong in Jira or Github)
The print.tpl was missing most of the new regions, adding them fixed the problem of scripts not loading.
But then I encountered a new problem - the first tab was attempting to load the current page via ajax rather than realizing that the content was already there. After a lot of head-scratching I finally tried removing the <base> tag from the print.tpl header and that fixed it. I don't know much about this tag but based on reading a few docs about it I *think* it was both unnecessary and was being used incorrectly (should have pointed to the current page instead of the base url) and that it should be safe to remove.
