Support irb >= v1.2

When using irb v1.2.3, projectile-rails-console does not work. The inf-ruby buffer shows what looks to be a control character, and I can't interact with it:

When I invoke a rails console through the inf-ruby-console-auto function of inf-ruby, it works. Looking at the code for that package, it passes the --nomultiline option to irb when the version is >= 1.2.0:

If I set projectile-rails-custom-console-command to "bundle exec rails console -- --nomultiline", projectile-rails-console works as expected:

Thanks for pointing this out.
