Added use-times.set-reset-value-by-default option in config.yml file. If set to true, product default buy / sell times will be set to reset value set in product configs or default value set in config.yml file.
Added use-times.max-value-for-total-only option in config.yml file. If set to true, max value set in product configs or default value set above will only work for total placeholder.
Added buy-times-max-value and sell-times-max-value support in product configs. You can set maximum values for buy times and sell times, and when the maximum value is reached, the plugin will no longer accumulate buy times and sell times.
