Initial commit for adding a DevNet authenicator network
Other changes needed to support a new DevNet
More progress on DevNet.
You can now connect an existing Login to a DevNet login if you are already logged into it.
Still need to make it so you can sign in as another user without first having to associate a DevNet account.

Modified the DevNet login URLs to point at /on/devnet/login.html
(might drop the .html before we're done, and will likely delete redirect)
Made another step forward, can now create accounts using DevNet.
Next (and final?) step is that if an existing user tries to opt-in,
discover their account through the submitted screen_name and connect the DevNet account
rather than trying to create a new anonymous DevNet user.
Finish off making DevNet work as I expect to.
Added some language and instructions to the DevNet log in page.
Moved DevNet to top of the default list of networks.
Redid the work to put the DevNet first in the list on the GitTip index page
Changed spacing to make things line up better
