New @export_array for giving names to indices

[miv391]

My problem: I have an enum for character states and an array for movement speeds for each state.

enum State {IDLE, WALK, RUN}
var speed: Array[float] = [5, 10, 20]

I want the array to be editable in Node Inspector. Like this:

@export var speed: Array[float] = [5, 10, 20]

Now the problem is that the editor shows

0    5
1   10
2   20

and I need to remember that 0 is idle, 1 is walk and so on. It would be much better if I could assign names for the array indices.

My proposal is to add @export_array.

@export_array("Idle", "Walk", "Run") var speed: Array[float] = [5, 10, 20]

Now the Node Inspector would show:

Idle    5
Walk   10
Run    20

Rules:

• Index naming starts always from 0.
• If you give less index names than the array has items, the rest use index number as usual.
• If you give more index names than the array has items, the additional names are just ignored.
• If the name is empty string, index number is used.

Unless the order of the values is absolutely essential, I'm pretty sure using enum-keyed dictionaries not only solves this problem but also makes the rest of the code cleaner.
