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

Batch #3420 by Lumen: 0 byte-identical, 3 confirmed by peer review.

- fn_07076 CCompetentia::Slot04: logic confirmed by peer review
- fn_07079 CCompetentia::Close: logic confirmed by peer review
- fn_07080 CCompetentia::Slot01: logic confirmed by peer review

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