Console aliases short and simple

[danmaksimov]

You can create file with name '.iex' in root project directory and put aliases and imports there.

Thanks for this contribution :)

This is a good idea for development environment, but I use the Console helper mostly in staging and production environments, which gives me two problems with an iex helper:

• I would have to deploy my "local" iex helper to production
• I don't want aliases and imports per default when opening a shell in production.
