Allow reporter to select a choice of URLs to report

Related issue:
- uBlockOrigin/uBlock-issues#1836

The URL to report can now be picked from a list of related
URLs in order to allow the reporter to publish edited version
of the reported URL.

Additionally, the hash, user name, and password which could be
present in a reported URL are always removed.
