Append index to original name when node names conflict instead of renaming

[OscarCookeAbbott]

One of the annoyances I currently encounter when instancing multiple scenes, for projectiles and such, is that all but the first instance is renamed to @<Type>@<Index>, such as @Node3D@32 or @Timer@47. This makes it difficult to track what is happening, especially when debugging.

Could we change it so that the @<Index> is just appended to the original node name?

For example instead of Enemy, @Node3D@13 we would get Enemy, Enemy@13 etc. We could also maybe consider changing the @ to a # to make the reason for the addition more intuitive to new users. Many other game engines and frameworks use a similar method to handle name conflicts.

I am not against your proposal but I want to point out you can address this somewhat yourself by setting the name property:

	var a:Node = Node.new()
	print(a)
	a.name = "Hello"
	print(a)

<Node#45197821329>
Hello:<Node#45197821329>

This is already supported, you just need to enable it, see add_child, calling it with add_child(my_child, true) makes this work correctly
