Adds new undershirts, jeans and pants by WalterJe, ports undershirts and pants from NT by JStheguy, ports the clothes vendor from NT by Ike709 and JStheguy

These were made by WalterJe and JStheguy. Credits go to them.
Also ports the clothes vending machine from NT, and adds it to the locker room, replacing the food vendor. Credits to Ike709 for the clothing vendor, and JStheguy for the clothing vendor sprites. Credits to WJohnston for the vending restock icon.
Note: I renamed the Pogoman shirt and the Band shirt in order to comply with /tg/'s copyright policy.

EDIT: Removed the white ian undershirt under request from a head coder, because there are too many ian shirts.
