Merge pull request #804 from xi/feature-clean-up-notification-settings

clean up notification settings
allow to explicitly set overlay-${size}

This is already sometimes set using JavaScript.
It is used to apply custom CSS.
use overlay size small for event carousel and event streams
check if overlays exist before executing javascript on them

this prevents javascript errors
use overlay_size on some more controller actions
add badge edit/manager permissions
check for specific permissions rather than admin for badges
typo
