QoL enhancement for the event editor.

[Justn53]

Is your feature request related to a problem? Please describe.
If you have Sprite animations or use different frame counts for sprite animations it is not able to be used for events.

Example:
Sprite1.png = SpriteAnimation.Normal = 6 Frames
Sprite1_idle.png = Sprite Animation.Idle = 3 Frames
The event editor will always look for 6 frames but if you only select the normal animation it will never use any of the other animations for the same sprite name.

Describe the solution you'd like
For the event editor to use the same logic as other entities when it comes to sprite animation frames and/or the ability for the editor to know how many frames to look for when a sprite animation is selected in the event editor.
