Run OpenProject on OpenShift

I made some minor changes to allow OpenProject to run on OpenShift.  I need a few more people to test it, and then I am going to submit it to be an OpenShift Quickstart.  Installation Instructions:

1) Create a gear using:
$ rhc app create <NAME> ruby-1.9 mysql-5.5

2) Go to the gear's git repo (created as part of the process above) and clone the openproject_openshift repo into it.  

3) Push the 'openshift' branch of this repo to the openshift gear, it will begin the installation process.  Warning- it does take nearly 20 minutes on a small gear
$git push test openshift:master -f

`ENV` missing for the port
