== Adding MF/PL statement check box

In order to add a check box to have users agree to the MF/PL Statement of Unity I edited two files: `actions/register.php` and `plugins/OpenID/actions/finishopenidlogin.php`. To view the exact changes I did check the `mayfirst` git branch on howard, e.g. like this:

{{{
$ ssh root@howard.mayfirst.org
# cd /home/gnusocial/social.mayfirst.org/web
# git branch # this is just to check we are in the correct branch
  master
* mayfirst
# git diff master actions/register.php
}}}
