New Settings

Default sorts, tags on "all" view, mobile nudges and the Nudger service itself have all been added.  Feel free to test it out & let me know.  The only final piece before opening up the Beta is to GROUP nudges into 1 send per day.  This will cut down on the email quota with GAE but will inevitably cut into the CPU quota.

I already anticipate quota problems with more than 20 active users.  Hopefully by that point Google will increase their resource quotas (or sell more resources).  In the spirit of "Getting Real" running out of resources is a good problem to have.
