Toggleable account option to "check all" for mass release

I support a select-all release option, but I can't go into detail for my reasoning while still remaining neutral.

I'm going to go with no support. I see the individual clicking as an added safety feature. Since you have to click each one, you're more than likely to see each pokemon's tooltip, which is a good way to check whether the pokemon you're clicking is actually one you want to release. Plus going slower helps keep people from making mistakes.
