New feature - User permissions register

Add a hyperlink for each user listed in the new ‘…/admin/users’ panel to display a new user permissions register displaying all of the contract level permissions (i.e. party and role) for that particular user with the option to remove the user from one or more of the contracts listed. Currently it’s not possible to determine which contracts a particular user has access to without checking each of those contracts individually. Having the ability to check and remove permissions in one place would significantly reduce the time spent administering permissions and reduce the number of support tickets.
