Updated list edit/add modal to be more user friendly. Added titles where necessary. Spaced out components/divs. Added text buttons instead of checkmark and plus icons for list titles. Updated title where list is empty of accounts/posts where user can click to add people to list. Added add/remove to list from account action dropdown
