Deleting Key Map Should Also Delete Launcher Icon

Developer TODO

• [ ] delete launcher icon when deleting key map

Once the key map has been deleted there's no need to keep the icon on the home screen, if one was saved, so it should get deleted as well.

Same for when you just turn off the access for other apps on the last screen.

I'm not sure I'd want to do the latter. I can foresee someone playing around with options in the app and may not necessarily want their homescreen layout being messed up when they temporarily turn off the option, but maybe turn it on again later.

Good point. What you could do is add a dialog asking, do you want to delete the home icon.
