Use @LinkedTimer for the timers of linked classes

The repeating timers that linked classes and the plugin main classes started
once for the whole runtime now use @LinkedTimer, on Spigot (BauSystem,
SpigotCore, LobbySystem, MissileWars, TowerRun, Teamserver) and Velocity.
The FightInfoPacketSenders of MissileWars and TowerRun are linked themselves
instead of being started by the main class.
