Generate bin files

[elia]

Generate bin/rails bin/rake bin/setup bin/update bin/console scripts, possibly also bin/server and bin/release (see the original PR)

• Won't add bin/server because bin/rails s is easy enough.
• Won't add bin/release because the release procedure it's not clear yet.
• Overcommit has been added to run checks (including Rubocop) before commits

Ref: #11

@elia I'm okay with the bin files, but not a huge fan of Overcommit tbh. I find that using that kind of tool slows down development because you often don't want to run checks for each commit, but only on the final PR, which is where Hound and similar come in handy.

Since most SaaS tools are free for open source projects, I think we're better off simply enforcing Hound on all solidusio(-contrib) repositories, which will probably be a part of #5.

In the meantime, could you split the two changes so that we can merge the bin files right away and keep Overcommit on hold for the time being?

[elia]

@aldesantis sure, I'll extract overcommit, my take is that I hate the noise that hound generates on the PR and the earlier I get feedback the better, also I would encourage having linted code in each commit, and delgate to the use of -n where it should be skipped.

But of course Hound will be way faster than checking rubocop as part of the CI. 👍
