2648	When adding object to a relation, show a warning if it's already a member of it.	Ldp	team	"Since we can now have multiple occurences of the same node/way/relation as a member of a relation, it's very easy to erroneously add duplicate entries. When removing the duplicate, in case this was a mistake, all occurences of that member are removed from the relation. This shouldn't be done, and it's counter-intuitive as well.

Either remove only the entry that's selected, or at least ask the user ""This member is in the relation more than once. Do you want to remove just this one, or all of them?""

Also, but this is more of an enhancement, but still very related: when adding a something that's already in the list, make that fact known to the user. ""This node/way/relation is already a member. Do you want to add it again?"""	enhancement	closed	minor		Core	latest	fixed		Gubaer
