Implement remaining subcommands

[ebkalderon]

The following subcommands panic emit an unimplemented! when executed without the (-h | --help) flag:

• deploy - Compresses and deploys the project as a distributable program
• module - Adds or removes engine subsystems

This issue will track the development status of these commands.

@ogoding If you have any suggestions or questions regarding the deploy subcommand, feel free to post them here. It can get quite busy in the Gitter chat sometimes. 😄

@ebkalderon I think this issue should probably be split up into separate issues as I don't think there is any overlap between them. Nothing else comes to mind, other than that I'm still working on the deploy command.
