Upgrade Guide v4->v5

There are only the following breaking changes between Uniform v4 and v5:

• Form data is now HTML-escaped by default in the Dump, Email, Log and Webhook actions. Set the new escapeHtml option to false to disable escaping.

• The data() method of the form now HTML-escapes form data by default. Set the new third argument to false to disable escaping.

That's it!
