Don't require using application_name before options

When I create new rails app it usually goes like this:

```
$ rails new --skip-something teh-app
Options should be given after the application name. For details run: rails --help
# fffffffuuuuu
$ rails new teh-app --skip-something
```

This pull requests fixes the situation to make it work more like this

```
$ rails new --skip-something teh-app
      create
      create  README.rdoc
      create  Rakefile
```

I'm not really sure if we support anything which can break after this change, if not I will gladly commit this to master.
