Renew API Key action breaks on development release (660672a)

[MisterMartin]

Logged in as admin@chordsrt.com. When I mash the "Renew API Key" button, the users_controller breaks. params seems to be missing.

Good catch. This is a result of changing from link_to to button_to within a form object. The form treated the button as a submit button and it was calling the update action instead of the one to reset the API Key. I changed it back to a link_to with styling consistent with the buttons on the page and will put it in with the DOI fix.
