Correct Nginx Issues

### Files added to start script
1) Had to add build and deploy to .openshift\action_hooks\start. Adding
build corrects repo not building after push. Adding deploy corrects
issues with nginx.conf.tmpl not being copied after build

### Updated Vars
2) Updated vars in nginx.conf.tmpl. For whatever reason, these vars were
not being converted by perl script in deploy. This was discovered by
comparing nginx,conf with vim.
