This update adds support for PlaceholderAPI:
%dragontimer_nexttime% and %dragontimer_nextmap% display the next spawntime and the world in which the spawn takes place.
%dragontimer_playersnexttime% displays the next available spawntime for the world the player is in.

New command to query next spawntime for a world: /dragontimer getnexttime [world]
New feature: timelimit for the dragonbattle !
Fixed a bug for Multiworld support.
