Always prompt user to import as animation or as layers like other paint applications

[jestarray]

Aseprite tries to group related frames like this:

goblin_walk_0.png
goblin_walk_1.png

and prompts you if you want to import these combined as an animation but it should just prompt you all the time you drag multiple images in.... because i have a scenario where:

// these are unrelated because of the _200 and _400
goblin_walk_0_200.png
goblin_walk_1_400.png

// these are imported in a new tab for some reason but they shouldnt because they relate to the goblin sprite
goblin_attack_0_200.png
goblin_attack_1_300.png

I wrote a script for this but at some point this should be built in.

As far as I know there isn't a friendly way to import multiple images as layers.... You have to
Layer > New > New Reference Layer from file > Select the file > Create a new layer and merge it down(because a reference layer cant be edited until it is cloned) . This is about 7+ clicks... and if your sprites are composable(e.g a shirt layer, head layer, pants layer) are all separate, this is a real drag..

The default behavior now is that it opens anything you drag in as a new tab if it cant detect they're related. Again, just always prompt the user whether they want their selection of images to be:

1. Imported as an animation(all frames dragged in are related)
2. Added as layers stacked on top of each other

paint.net, gimp, other image editing programs have a way to do the following
