Implement Heroku-equivalent commands

[stuartpb]

definitely

• apps:create
  • anonymous app creation?
    • I'm going to make this something you opt into by installing a plugin with a random word generator hook. If you don't have one, running apps:create without a name fails.
• apps:destroy
• apps:rename

probably

• apps (command - lists apps)

probably not

• apps:info

almost certainly not

• apps:open (considering we're server-side, domains:link is probably the best we can do)

maybe another plugin

• join, leave, lock, unlock (ownership things)

You know, I'm pretty sure we can do apps:create without Git. Just make the app directory that a later Git push will interact with.

Or, apps:create does the Git initialization. (Then the git-hooking plugin should probably be replaced with a git-passthrough version that rejects pushes to repos apps:create has not created.)

I think acl would be a cool alternative plugin for join, leave, lock, and unlock.
