actionhero REPL

*part of version 9.0.0*

actionhero now has a REPL!  Running `grunt console` will load up a version of action hero in your terminal where you have access to the `api` object.  This version of the server will `boot`, `initialize`, and `start`, but will skip booting any `servers`.  This will give you a full environment to manually take action.

The REPL will:

- source `NODE_ENV` properly to load the config
- will connect to faye/redis, and load any user-defined initializers
- will load any plugins
- will **not** boot any servers

If you are familiar with rails, this is very similar to `rails c`
