Fadeless needs options

[Madis0]

What config to change

Fadeless either needs

• a toggle
• a slider/number value for animation
• to be replaced by a different mod

Why should it be changed

Per #748, it was clear that 41% of users do need some kind of option or configurability for the mod, as it is very visually impactful and can make-or-break the perception of the modpack.

Additional details

613 may get an option for this, but also the dev of Fadeless itself discussed the possibility of https://github.com/DerpDerpling/Fadeless/issues/4

RRLS got the option for it, so Fadeless will be removed.

Done in 5.6.0.
