Server: Restrict to Depths of Darkhollow

[spidey1170]

I've been doing a bit of research on this, and have decided to support only the Titanium client.

First, I changed the rules_values:

World:ExpansionSettings          1023

I found this from a 2014 post by chssrhb. I hope it's correct, so far, I can still login and nothing seems out of the ordinary.

Then, based on a Grumpy post from 2017, I changed:

World:UseClientBasedExpansionSettings          FALSE

And, so far, so good. Next, I had to find the max level for Depths of Darkhollow. Many searches on the Internets turned up little on the specifics; however, I did find one post on the Daybreak forums that gave max level by expansion:
