Changed it so runway commands are run from any repo

[n0nag0n]

Runway is now just a shell, and each of the commands lives in a prospective repo that's defined in the paths for the runway repo itself.

So there will be a few commands in this core repo, there will be some in the active-record repo if you choose to have that repo in your project, and based on the dependencies you add, if they have specific commands for runway (usually saved in the src/commands/ directory), you can now use them automatically! :partying_face:

woa, more dependencies of the dependency..fine :D

So this is only a dev dependency. When you install flightphp/core, it does add the dependency. I had to add it as a dev dependency so it could be properly unit tested.
