rocket 0.1.0: New formula

Rocket is a cli for running App Containers.
Thanks for the reminder. Will do. How do you feel about `%W` when the number of words is great than say five?
i.e.
```ruby
system *%W[this is a command with many spaces]
```
rather than
```ruby
system "this", "is", "a", "command", "with", "many", "spaces"
```
