Add Sprite Frames property for TextureRect node

[valkyrienyanko]

I have a coin using the AnimatedSprite node because I like the Sprite Frames property where I can supply one image file containing a horizontal list of all the sprites.

But using the AnimatedSprite node makes me use a Control node with a horizontal padding value that I have to manually guess.

The TextureRect node would fix this solution but then I would have to specify each individual animation frame and I would have to go into my image editor and separate the coin frames into individual files.

I propose that the TextureRect node gets support for a Sprite Frames property like the one from the AnimatedSprite node.

You dont have to "split into individual files", you just change the region_rect of the texture rects sprite.

I can't find this region_rect property
