When we removed script/rails and introduced bin/rails, we accidentally
introduced a regression. If you install Rails 4 as a gem, then try to do
something in a Rails 3 application:
$ rails g
This will throw the 'please type rails new foo' message rather than the
proper generator documentation message. This is because older apps don't
have bin/rails.
Therefore, we now *prefer* bin/rails, but still search for script/rails,
and exec the one we find.
