This Dangerfile ensures that commit authors write good commit messages.
We also prevent the use of Emoji, since these add no value and may not
always be displayed properly.
Merge commits are currently ignored. In the future we most likely want
to stop using these, but this is a separate discussion, hence we ignore
them for the time being.
The rules enforced by this Dangerfile are based on the article found at
https://chris.beams.io/posts/git-commit/. For more information, refer to

It's possible for a Ruby file to be empty and thus `gets` returns `nil`.
Also indents the Markdown since we're using `<<~` and removes an
unneeded variable.
Instead of only checking for migrations, we now check for a variety of
files and directories that require a database review. We also include
some steps on how to make sure changes are reviewed.
