Cleanup README.
Make passivetotal service work.

Initially written by Brandon Dixon. This is a heavily cleaned up and working
version of his code.
Assign copyright to Brandon.

This never was copyright MITRE. Brandon wrote the original and just copied
an existing license file. I've just cleaned it up. :)

Also, remove the distribution statement derived from MITRE public release
process.
