Subject: [PATCH] Decompile 4 functions in
 Source/Contents/Effects/MagnumBreak.cpp,
 Source/Contents/Effects/MagnumBreak.h, ...

Batch #3836 by eAthena: 4 byte-identical, 0 confirmed by peer review.

- fn_18951 CMapChainEffect::Slot06: byte-identical
- fn_18957 CMappillarEffect::Slot06: byte-identical
- fn_18966 CSquareRangeEffect::Slot04: byte-identical
- fn_18975 CSteal::Slot04: byte-identical

Merged automatically: every function is byte-identical to the original.
Adds to the build: Source/Contents/Effects/MagnumBreak.cpp, Source/Contents/Effects/MapChainEffect.cpp, Source/Contents/Effects/MappillarEffect.cpp, Source/Contents/Effects/SquareRangeEffect.cpp, Source/Contents/Effects/StealEffect.cpp, Source/Contents/Effects/MagicFloorEffect.cpp
