Use one-time log-in links in widgets

Problem/Motivation

Widgets show the user name, password, and log-in link. I would expect the log-in link to log me in, but it takes me to the page to put in my user name and password.

Steps to reproduce

1. Launch app.
2. Click log-in link.

Proposed resolution

Either remove the log-in link or use a one-time log-in link generated by Drush:
drush uli -l $DP_HOSTNAME

Remaining tasks

User interface changes
