Miasmata: Add shaders overridden in d34dd's fix

I've previously determined that some of the overridden shaders have changed in
one of the game's updats and have a new checksum - I've added symlinks to cover
the old checksums.
Miasmata: Add 3d4dd's fix

Renamed shaders to match latest version of game:

2E6C14E9.txt -> 6B0F82ED.txt (UI)
A1AFEA52.txt -> 46092D17.txt (Skybox)

Looks like the indentation was removed - to make sense of the change use
'git diff -w' or select 'Ignore space change' in gitk
Miasmata: Update DX9Settings.ini for latest HelixMod
Miasmata: Add water vertex shader dumped from game
Miasmata: Fix water glitch without needing Aion profile

Using the Aion profile somehow fixes the water as well, which is how we did it
before. Now we don't need to :)
