Added

• Weapon levels. Every weapon item collects XP from hits and kills and levels up. Each level adds a bit of damage and takes a bit off the cooldowns. The level and progress are shown in the lore and in a message when it goes up. Everything is under leveling in config.yml: enabled, base-xp, xp-step, max-level, damage-bonus-per-level, cooldown-reduction-per-level, xp-per-hit, xp-per-kill, xp-per-player-kill and lore-format.
• PlaceholderAPI support, optional: %weaponsultimate_holding%, _weapon, _weapon_id, _level, _xp, _xp_next, _xp_total, _cooldown_<trigger> and _weapons_total.
• Update check. It looks for a newer version on Modrinth and Hangar and writes a line to the log. updates.check turns it off, updates.auto-download also downloads the new jar into the update folder, to be installed on the next start. Off by default.
