Allow more customization with infected models

The new shorts that the Virus models have (despite just being for censor purposes) don’t look bad at all and I think it would be pretty cool if the colors of the Virus clothes matched the color you set for your character’s clothing instead of being random.

In addition to this, I think bringing back the ability for the infected to wear appearance items (and even giving them shirts? maybe?) could add a lot to the game and would improve character customization, which is one of the main aspects and selling points of the game.

We’re planning on doing more with the upgrades.
