Fatal error on new individual form, new contribution, new membership...
Something very recent is causing a fatal error on the new individual form. I think it's between commits 0f86b677 and 95266ab3 but I can't see what. It's not just my local - I can see it on this PR test site for example: http://core-17766-50jo7.test-1.civicrm.org:8001 (admin pass TVCRm1QqkGcQ). But I don't think it's that PR, it's just an example of a recent test site where I see it.
It has to do with calling CRM_Core_SelectValues::date() with $type='mm/dd/yy', whereas normally it's a word, like 'birth'.
