Virtual Stock (VStock) for Snipers Only

In order to better the experience of using sniper rifles in Pavlov and reduce the jankiness, there should be an option to enable VStock for sniper rifles ONLY, to eliminate the need to enable and disable VStock whenever one acquires a sniper rifle. This would make it much more immersive when using sniper rifles, and will not affect regular VStock users as it simply adds an option and does not take away.
