* Move shadow packs to main pack
As talked about in #143
* remove splatoon shader edit
Same shader is also in the main pack... confusing
* Add end-screen fix for shadow scaling
Also added a label. Could mean that there's a need to scale a different shader like
https://github.com/slashiee/cemu_graphic_packs/issues/149#issuecomment-379528843 suggests, although I'm not sure anymore.
Should now pretty much fix all the blurs I could see (although the main menu (maybe other scenes too) has multiple blurs depending on the weather, not fixing that one tho).
