playtime

- Fix an issue with MySQL where data wasn't loaded correctly.

• I recode it so kinda everything changed.

• Save player join date

• Won't track playtime of afk player (configurable in config)

• Reward system changed: Repeating reward that run each X times, One time reward that run only 1 times.

• New placeholders:

%playtime_leaderboard_<1-10>_name%

%playtime_leaderboard_<1-10>_format%

%playtime_is_afk%

%playtime_join%

%playtime_join_<SimpleDateFormat>%

• New permissions:

playtime.exempt.gain

playtime.exempt.reward.repeating

playtime.exempt.reward.onetime

• Some other small change, so yea it's should be better
