* pollinate:
  - remove sourcing of an rc config file from $HOME, per security
    review from Seth Arnold
* pollinate.1:
  - update documentation to note that multiple servers can be specified
    on the command line
* debian/pollinate.default:
  - use the entropy.ubuntu.com beta site for testing
  - note that we're specifying the --insecure option here, as this is
    very much a work in progress
* debian/pollinate.upstart:
  - start pollinate when we have networking up and running, or
    when we start ssh
* pollen.go:
  - drop the nanosecond timestamp collection on the server
  - a good server should have real entropy hardware, and a busy server
    will have network traffic entropy already captured by the kernel
  - Suggestion by Seth Arnold in a security review
* debian/pollen.default, pollinate:
  - drop timestamp based salting, not terribly valuable
  - per security review by Seth Arnold
