I'm not sure if from a current code perspective the bonuses and such
from each level are just added on or are tied to the level. I had
expected that if you left a guild all bonuses would go away, and that
the things you learned would likewise vanish. If this is not how
the code currently works, and it's too much trouble, then of course
it's a lot of work... and likely not worth it, but, hey, I just give
ideas, that's all
