Update urreg to use curl

There will be major changes to urreg in many ways, including these:

* Fix quoting
* Turn the ruby login.rb call to a curl request
* Add more requests to come closer to matching what the site does
* Update comments
* Add headers gotten from Firebug in comments
    - Don't include the headers in the actual curl requests, because
      they would cause HTTP 400 Invalid Request errors
* Add more functions (create_url, send_request)
* Add a verbose mode
* Set a cookie jar for curl to use
* In general, save more output to files
* Fix misc. bugs
