Add Docker image for Jenkins

This is a customized image of Jenkins for Docker that will fetch
these scripts and automatically run the Jenkins job builder from
jobs specified in the jenkins directory.  There are some caveats
for running this image in boot2docker; see README.md for details.
The image does consume a large amount of memory and disk space!
