Subject: [PATCH] Decompile 2 functions in
 Source/Contents/Effects/SmokeEffect.cpp,
 Source/Contents/Effects/SmokeEffect.h

Batch #3993 by Yommy: 2 byte-identical, 0 confirmed by peer review.

- fn_19178 CSmokeEffect::Slot06: byte-identical
- fn_19180 CSmokeEffect::Slot04: byte-identical

Merged automatically: every function is byte-identical to the original.
Adds to the build: Source/Contents/Effects/SmokeEffect.cpp
