Sign alias should not include wall and floor signs when not specified

Found by @arcsin0.5 on skript chat discord.

When using oak sign or spruce sign as an item, eg: giving it to player or setting a slot, the alias can resolve to either floor sign or a wall sign, and a wall sign cannot be given as an item. So half the time giving a sign or setting a slot will silently fail, when not specifying floor.

The alias should always return a floor sign, like torch always returns a floor torch.

[floor] torch¦es = minecraft:torch
any torch = floor torch, north facing wall torch, south facing wall torch, east facing wall torch, west facing wall to…

any oak sign should still include wall signs, but oak sign alone should not.

honestly I think something needs to be done to stop band aiding it.
Just forcing it to default to floor (whatever) when only (whatever) is used doesn't solve the underlining issue.

A method for forcing wall (whatever) or hanging (whatever) to their item format needs to be added not only for those but any as well. if I understand enough it means give player any sign would end up giving no item meaning we're just covering up the issue.

#88 addresses signs. If this is valid, torches would need work.
