[Open Assets] EHZHangout v18

And here we go! The last major update of EHZHangout! The mod will only receive bug fixes (if there's any to fix) and a port to 2.3 (I think I won't be here by the time 2.4 releases, though if anything, someone else could port it) from now on. Maybe some minor improvements, if necessary. I don't know. Hopefully not. Anyways, let's see how this old Starshy mod gets sent off!

Global:
- Updated the level select pictures
- Removed the "Hangout" gametype from the level headers; this doesn't mean it can't be used with Hangout servers anymore, though

Emerald Hill:
- Changed up the exteriors of the houses
- The violet house's interior is now separate; you get teleported into it to enter it. This improves framerate around the exterior
- Changed up the wood area's look
- Moved away some objects at the violet house's exterior to avoid clipping
- Made the sinks and the bathtubs actually start pouring water upon getting near/entering them (in the bathtubs' case)
- Changed up the Cosomania area; there's now a rocket that, upon everyone entering it, will traverse them to Cosomania!
- Some other lighting tweaks
- Added doors using the "PolyObject Door Swing" linedef type in both houses
- The other kind of waterfalls in Hidden Palace Act 1 now, instead of using an animated texture, use Linedef type 502 to be scrolled!
- Additionally, the timing of the dripping waters have now been changed; the amount of the dripping waters has also been significantly cut down

Cosomania:
The map has been completely revamped. No, the layout isn't completely different, it's still mostly the same, but now it looks better than ever! Check it out!

I have also mentioned that I'm working on a Christmas patch for the level pack. It's still being worked on, but at this point, I decided to just release v18 out of the way. Enjoy!

Thank you for playing this level pack, and thank you, Starshy, for creating it!

This update brings you a complete Emerald Hill, with numerous improvements and even new stuff! Check it out! The Overview page was also overhauled, and you can see screenshots and gifs of the finished Emerald Hill.
Additionally, I fixed a missing midtexture in Cosomania. That's it for that map. I'm not sure if I will revamp it in the future.
Enjoy!

Aaand I had to release an update shortly after it got released...

• Removed the secret wood area at the 2nd house, as I've found out from Starshy himself after releasing v17 that it was actually stolen from an old hangout map named Rainbow Pebble Beach made by a person named indigoJerboa/Mirustal. The area was later removed from the level pack due to that. Sorry Mirustal for accidentally stealing a part of your map... Also, Starshy was like 11-12 when he made this level pack. He has since become a better person than when he made it. He also played this new version of the mod and he said that it's great!
• Made some teleporters in Emerald Hill retain your momentum. I already wanted to include this in v17, but I forgot and couldn't replace the file with that change
• Tweaked O_EMEH and O_EHZHOS. Now they're smaller in size, are slightly quieter and have slightly different loop points
