Update 18 Changes

- New Main Menu Theme and Background Picture

- New Weapon Sounds:

- Colonial/Warden Long Rifle

- Volta Repeater

- Warden Revolver Rifle

- Warden Automatic Rifle

- New sounds for the Listening Kit and Intelligence Center

- Lots of Misc. Volume Tweaks

For those wondering about new tank engine sounds, for whatever reason the devs decided to make both new tanks use the sounds of the Colonial LT. It's probably an oversight, but whatever.

Also, for those unaware, I'm in college/have a job now and recently decided to take a bit of a sabbatical from Discord to focus on IRL things. I'll still keep this mod updated but don't expect much from me in terms of messages for a while.
