Throw an error if a module exists twice

Sometimes when developing you end up with a duplicate copy of a module somewhere, and this causes a lot of headscratching when you make changes in one copy and Drupal is actually using the other one. There doesn't seem to be a good reason to allow this situation where Drupal just arbitrarily selects one version of the module to use, so to avoid many man hours of debugging time we should detect this situation and report an error rather than leave it for the developer to track down.
