Forgot to mention the project

1. Make it so the user can decide (advanced options only) if they want one
bridge per tap or one bridge per host
2. You will likely need to reorganize org.petitecloud.net.NetIface.reset()
3. Keep track of what tap goes to what bridge (just same device number
might do it)

Neither I or Dee will have time for this for a few weeks.
