This commit: - Continues my AKOS relabeling task and adds some documentation and missing information; - Renames the codec functions from codec1, codec5 and codec16 to something more expressive; - Add '_' in front of private class members, when missing; - Changes "v1" names (unnamed variables supposedly coming from Ghidra or similar tools...) to something more expressive; - Renames related variables from foo_bar (or foobar) to fooBar (on costume.cpp, base-costume.cpp and akos.cpp).
