Add Arma3 shader that decompiled wrong, as a test case.
Manually fixed.
Three more reflection shaders, added to Alien.

These were found by looking in ShaderCache for reflectionSamplerReg_SMP_s.

They matched Mike's earlier technique, so I added the fix for these files, not knowing where they are used.

Seems to fix the Tram station floor reflections at least.
