Automatically move slow-growing cells to Fort

Sometimes there are cells almost finished but grow slowly because few players trace on them. It may accelerate tracing progress by moving cells to Forth when them grow too slow, saying

  • not finished longer than one week or
  • 24h growing < 10.

i like the idea but this also fluctuates with:

  1. how many active players there are (playing stuff)
  2. how many scythes are active and/or completing stuff
