Title: Allow RAILS_ENV override by servlet container

This way I wouldn't have to generate a different WAR for each
environment (production, staging, etc). I could set RAILS_ENV on
GlassFish, Tomcat, etc.

This is specially useful after a WAR has been validated on staging
and you want to copy it to production servers.
