move the autotmation scripts into gaworkflow.automation

move the autotmation scripts into gaworkflow.automation
the scripts that were providing the tools to automate running
the solexa pipeline were unfairly "priviledged" compared to the
components that wrapped talking to the pipeline commands and
providing the website, in that the other components were in
sub-packages while the automation was just in the gaworkflow
package.

So I moved them into the somewhat clearer "gaworkflow.automation".

The intent is that gaworkflow.automation contains modules
that make things happen without human intervention.
