Add accepts change condition

[Pikachu920]

Aims to add an easy to to see if an expression accepts a changemode

[Fusezion]

let me know if I'm over simplifying this but couldn't we just add ChangeMode as a enum in skript-reflect and do something like

%objects% supports %changemode% changer

if slot supports delete changer
if player's tool supports set changer

might be better to suffix modes with changer by default since idk if it'll conflict with related effects

since expressions and likely classinfos have getAcceptedChangeModes which returns a map it should be as simple as a null check

[Pikachu920]

getAcceptedChangeModes

getAcceptedChangeModes is intended for documentation purposes, not real logic

[Pikachu920]

skript-reflect actually already returns unwrapped Expression objects, but there hasn't been a registered classinfo for it

Only optional changes! nice work

Suggested change

	{"%classinfo% can be added to %expressions%", ChangeMode.ADD},
	{"%classinfo% (can't|cannot) be added to %expressions%", ChangeMode.ADD},
	{"%classinfo% can be (added|given) to %expressions%", ChangeMode.ADD},
	{"%classinfo% (can't|cannot) be (added|given) to %expressions%", ChangeMode.ADD},

Not sure if it's worth doing this, but if you agree, the other modes should be done as well, like clear for DELETE

sounds like a good idea. i can't recall if skript has a dirt can be given to player type syntax though. i'll have to double check so we dont accidentally cause a conflict if there is
