Mitchell Hashimoto 83917a6bb0 Added arg and arg_extra API to easy commands
Easy commands can now easily get arguments from the command line.

Using `arg`, you can get named arguments on the command line, such as
"--foo" or "-f"

With `arg_extra`, you can get any remaining arguments after a "--"
on the command line, which is a common pattern used to grab longer
parameters.
