  OpenShift, others).

Document rewrite rules for PaaS solutions
Use alias rule always

- I tested using the new RewriteCond and RewriteRule that were in the comments
  on my previous commit against a non-aliased host - and they work perfectly in
  that environment. As such, this is actually a better solution, as it will work
  in all cases.
- Documented the reasons for the rule in the file.

Alternate precedence order for ZF2 path

- It makes more sense to assume that if ZF2 is actually _in_ the
  project, to use it, and only if not present start looking at the ENV
  and php.ini settings.
