Makes the MP Beret clickable. (#3622)

# About the pull request

Title.

# Explain why it's good for the game

Trying to click a tiny little sprite to take off a piece of headware is
bad. Seriously.

Other hats that suffer from this that I DID NOT fix because I'm not a
spriter and I cannot make new sprites. (This one is from an old version
of the dmi file that I had when I made my previous PRs);

-Normal and tan berets.
-Boonie Hats
-Doo-Rags.
-Patrol Caps
