Title: Added a generator option to skip the public/index.html file

Squashed the branch from @ivanvanderbyl as requested in rails/rails#2649 and rebased on master.

Branch is largely as per the previous pull request except for fixing the broken test that the commit from @parndt introduced on that branch (`assert no_file` -> `assert_no_file`).
