Placeholders

With PlaceholderAPI installed, LuckyDrops records every open by drop type and the rarity it finished at, and exposes the running totals:

Placeholder	Returns
%luckydrops_opened%	Total drops opened (all types, all rarities)
%luckydrops_opened_<type>%	Total of one type
%luckydrops_opened_<type>_<rarity>%	Drops of one type that finished at one rarity

<type> is a drop type id and <rarity> a rarity id from that drop.

%luckydrops_opened_default_mythic%   ->   4

Unknown or never-opened combinations return 0, never blank. Stats are kept even if a drop type is later deleted, and live in playerdata/<uuid>.yml.
