[web2py] nginx+uWSGI+Web2Py for Ubuntu Precise 12.04

[orsomannaro]

I made some modify to setup-web2py-nginx-uwsgi-ubuntu.sh script to fit it to Ubuntu Precise 12.04.

Differences with the previous script:

- install nginx and uwsgi from Precise reporitory
- load python plugin in uwsgi configuration file for web2py

setup-web2py-nginx-uwsgi-ubuntu-precise.sh
