Added tests mentioned in #4261.

Git squashing would make this a bit prettier:

There are also:
alpha.bewelcome.org
test.bewelcome.org
trac.bewelcome.org (refused)
fox.bewelcome.org (refused)
downloads.bewelcome.org (mismatched)
www.bewelco.me (mismatched)

The content on (www.)bewelco.me differs from bewelcome.org.

Please use comments to document all problematic domains on the top of the rule.
Our style guide requires tabs instead of spaces.

@thisismeonmounteverest would you like to finish this?
Don't worry about squashing commits, we do this during merge.

@thisismeonmounteverest Are you still interested in working on this?

[thisismeonmounteverest]

If I don't have to do anything for it, yes. Otherwise drop it.

The process to get something in was way to complicated.

Unfortunately, this ruleset would need more changes before we merge it. I'm closing the pull request based on your last comment, but I've noted the domains in issue #3069 in case anyone else wants to include them.
