Convert lcd_activation callbacks to use the event system to allow for multiple parallel callbacks (for custom statusbar).

Increase maximum event count as we need more (I actually had a report about it during custom statusbar testing).
Removed corresponding functions from the core and plugin api. Bump min version and sort.
