Helmets no longer hide ears (#6125)

# About the pull request


This removes the HIDEEARS flag from the helmet.

# Explain why it's good for the game
Personally speaking, i've had alot of trouble looking for screwdrivers
(all engineers had it on their ears) and sometimes you cant or dont have
the time to look through the strip list. theres no further reason then
just that honestly.

Also i dont think our helmets are tight tight you can see ears in the
movies (yes i pulled the le movielike argument)
