Water & shader issues

[YoYo178]

ff_waterpolo required a whole color material overlay replacement on the tiles below water (from ff_color_<COLOR>_a10 to ff_color_<COLOR>_a40) to match sdk 2006 ff

water is invisible in ff_cz2
water body looks like a hole with fog inside it instead of actual body of water in ff_well
ff_openfire has transparent water instead of being slightly blue (this seems very related to ff_cz2, the reason it's not invisible in ff_openfire is because the water here seems to refract more than ff_cz2's water does)
(these are the only ones that were checked and confirmed, there might be more)

example on ff_cz2:

SDK 2006 FF

SDK 2013 FF

I'd be surprised to see how it looks in Garry's Mod, too... as that runs on SDK 2013.
