[16.0][ADD] web_editor_clean_url

[hbrunn]

This module allows administrators to configure cleanup rules for links
inserted by their users, as inexperienced people tend to just copy&paste
whatever they find in their address bar, which might contain data you do
not want to see published on your website, be it tracking tokens or
session identifiers.

Configuration

You find the configuration in Website / Configuration / Clean URLs.

For every configuration, you can fill in:

Hostname: allowing to restrict this configuration to some domain

Remove Query Parameter: removes parameters from the URL. Separate
with comma

Replace Regex: replaces a whole portion of the url

Substitution: if the regex contains brackets, you can refer to the
matched content with \1, \2 etc

Usage

To use this module, you need to:

1. Review the configuration
2. Edit a website page, insert links and observe they are transformed as
   configured after saving
