[BUG] Extended Upgrades "DealsDamage 1" filter in AllowedWeapons does not disallow heavy's lunchbox items or other class' jars.

[raandomguy]

Example:

ExtendedUpgrades [$SIGSEGV]
	{
		upgrade_DAMAGEBONUS
		{
			Attribute			"damage bonus HIDDEN"
			Cap					2
			Increment			0.25
			Cost				400
			Name				"+25% Damage"
			AllowedWeapons	// Restricts upgrade to specified weapons
			{
				DealsDamage	1	// All weapons dealing damage
			}
		}
	}

This should be unavailable for Scout's Mad Milk, Sniper's Jarate and Heavy's Sandvich, but it is available instead.
