This little helper script allows for easy ember cli development.
To see the options run `bin/ember-cli -h`
It allows you to proxy try.discourse.org with the `bin/ember-cli --try`
switch, which effectively allows for some development without a rails installed.
It passes on arguments to ember-cli so you can customize port and so on.
It makes the assumption that on local people are using `bin/unicorn` for
development. (it includes some extra discourse specific helpers)
