Theme Switcher + minor bug fixes — Last Train Outta' Wormtown Steam update #611280

Howdy! I hope everyone's been enjoying the Halloworm event! This is a small update to add a requested feature and minor bug fixes. Map Theme Setting - Added a "Map Theme" selector in the match settings panel, for those who want to play on the standard map theme. (Note: The Halloworm theme will still be available after the event ends via this setting.) - Cleaned up the match settings panel UI a bit. Minor Bug Fixes & Changes - Fixed the grave sand mounds being orange in the Halloworm map theme. - Changed the Hat vertical slider (in the Pardner customizer) to have the same ranges that the second hat does. (The first hat had a smaller range before). - Fixed ladders occasionally falling through the map. - The "Hide Worm Mouth" options setting now correctly works with the new Worm cosmetics.
