Title: fix for Procfile create/update: newline added to the end of content

This fix was made for a tiny bug fix.
For example, we have following defaults:

recipes:
- gems
- email_dev
prefs:
:dev_webserver: thin
:prod_webserver: puma
:mailcatcher: true

In this case we'll have following `Procfile.dev`:

web: bundle exec rails server -p $PORTmail: mailcatcher --foreground

So we just need to add `\n` to the end of each `Procfile` line.
