Re-introduce system executable

Similar to the last rewrite, we generate a new gem and do a directory
swap, while making sure to preserve important files like NEWS.md.

This branch will serve as a new base for us to merge into while we build
up an [application template][template].

This approach is largely inspired by [staples][].

-## Testing Generators
-
-There is a smaller dummy application at `test/dummy`. This application is used
-as a mounting point for the engine, to make testing the engine extremely simple.

-There are a number of [assertions][] and [helpers][] that make testing
-generators easier.
+## Testing the executable Locally

+To install this gem onto your local machine, run `bundle exec rake install`.
+From there, you can run `suspenders <app_name>` to test the current code.
