Superview tweaks

[thomasskinner93]

Superview needs some tweaks.

-1) When trying to preview an animation, currently(newest pinned release in channel with decompression support) we have to select model, then fragment(.bin), then anim slot,(animation is tied to the slot, unchangeable) for the animation to be playable. This is way too much work, I recommend reverting to 0.45's way requiring nothing but the model and a way to freely choose which animation/meta/persistent to play based on skeleton.

Newest version workflow:

1. Add anim files to packfile
2. Open .bin
3. Create proper anim slot
4. Path anim and meta
5. Save bin text
6. Save bin
7. Save packfile
8. Open superview
9. Load model
10. Find correct fragment/bin out of hundreds
11. Find correct anim slot out of hundreds
12. Anim is automatically loaded with meta and persistent

All of this just to VIEW an animation that may or may not be worth using, as opposed to 0.45's way which is:

1. Add anim files to packfile
2. Open Superview
3. Load model
4. Select animation
5. View animation
6. Duplicate, rename, path appropriate meta file
7. Save meta
8. Save Packfile
9. Import into 2nd packfile inside rpfm
10. Save in rpfm
11. Test in game

Way more work with way less pay off, by step 11 I'm in-game testing, as opposed to just now viewing the animation. Freely selectable meta is of high priority as well. The anim transfer tool seems to suffer from the same thing.
