Reflective water tweaks

[Cervator]

Found a few issues playing with the shiny new reflective water while merging in the changes from @overdhose that makes enabling it easy:

1. Reflective water + heavy fog = unhappy shaders (or something). See example below - I should probably dig up some logs or something if possible?
2. The side of reflective water is jealous of the top and also reflects ... the sky. Maybe side water should be either opaque or just transparent or something?
3. Should / is it possible for the reflection to be less absolute and let a bit more of the scenery below water show?
4. Looking at reflective water that looks "up" at blocks can seemingly look inside solid objects (looks similar to clipping into terrain and seeing only some rendered block sides with most invisible)

Pretty tho, and runs well on my system at least :D

Please, make this feature at least part of the rendering quality "epic", or maybe create an extra one :) To be part of "ugly" would kill lots of gpu's. Just saying, because I really like the game and I would hate it to become unable to play it because of the heavy graphics :)

It is actually a separate toggle from graphic quality entirely, and disabled by default :-)

Closing this as water reflection has recently gone through a bunch of nice tweaks :-)
