[Feature] Add option to delete after installing

[devnoname120]

Request

From my PoV keeping around signed IPAs is completely useless, I would rather only keep the unsigned/unmodified IPAs given that signing takes at most a few seconds.

Wondering if we should just have Delete After Installing instead as original request points out signing is very quick. PR above just adds it can adjust the change based on feedback. Thanks!

Hmm..looking at this change #654 which looks great btw I think it would be preferable to only have a Delete After Installing instead if we want to make the change. Without it I think we risk just losing the update functionality altogether if users opt to enable deleting both signed/imported(unsigned) apps.
