Emit a signal after animation completes

[Loufe]

Hey Alex,

I wanted to be able to run some animations during cutscene dialogue and couldn't find a way to limit an action to a single repetition. This was my best solution, though it's not perfect. With this code I'm able to play an animation, then await the new signal to know it's done.

I don't like using flags that much but I needed to do it this way to ensure I'm grabbing a sprite with the used animation (in the case of multiple sprites) to not brake functionality for people using the add-on that way. Make sure it's flagged to avoid sending the signal multiple times.

Also to note that I use the add-on purely in code (no scene tree entry) so the signal cannot be linked with a node in the scene-tree to achieve this.

Open to your thoughts.

I would say that this should be after the single spritesheet, because the AnimatedSprite2D already have a signal for animation_finished and we should use it instead of creating a new implementation. And it would be only one spritesheet, so only one signal emitted

Yeah that's a fair point. I still think the LPC class should funnel back the signal, as other might use a no-scene-tree-node based implementation like I do. Any thoughts?

I think this should be merged, just because of this: #20 (comment)
