Yet Another Bingo

Various bugfixes following the previous update:

• Fixed the spawn kit using multiple references to the same ItemStack object, which creates very confusing behavior

• Fixed "the end" spawn dimension timing out and crashing the server because it thinks the entire dimension is underwater

• Added stricter conditions for choosing team spawnpoints in the nether

• Added commands for some of the config settings, which can be changed after starting the game:

  • /bingo timelimit
  • /bingo wincon
  • /bingo elytra
  • /bingo itemdist
