Subject: [PATCH] Decompile 3 functions in
 Source/Contents/Effects/MapMagicZoneEffect.cpp,
 Source/Contents/Effects/MapMagicZoneEffect.h

Batch #4737 by eAthena: 1 byte-identical, 2 confirmed by peer review.

- fn_19112 CMapMagicZoneEffect::AddSpinner: logic confirmed by peer review
- fn_19113 CMapMagicZoneEffect::Close: byte-identical
- fn_19114 CMapMagicZoneEffect::Slot01: logic confirmed by peer review

Peer-reviewed-by: youko, Lumen
Accepted without human review: peers confirmed the logic ("same" ahead by at least 3, with 70% of the votes).
