2014.12.18 MSS Code Factory CFDbTest 2.1.12706 Account creation, device creation, and device deletion added to .war

I've added the forms for creating new accounts, creating new devices for an
account (and assigning the first device created as the default device for the user),
and also implemented device deletion.

Next I need to add facilities for changing the default device for a user,
and for editing/changing the public key associated with a device.

Then I'll need to enhance the device creation and edits to verify that
the submitted public key is valid and can be converted to a usable object
by Java's security APIs.  Right now it's just a multiline text blob that
doesn't get used for anything.
