* Separate growth factors for tunnel count and tunnel test time * Reduce growth factors, so probabalistic throttle would activate * Square probAccept values to decelerate stronger when far from average * Create a bandwidth stat with approximately 15-second half life * Make allowTunnel() check the 1-second bandwidth for overload before doing allowance calculations using 15-second bandwidth * Tweak the overload detector in BuildExecutor to be more sensitive for rising edges, add ability to initiate tunnel drops * Add a function to seek and drop the highest-rate participating tunnel, keeping a fixed+random grace period between such drops. It doesn't seem very effective, so disabled by default ("router.dropTunnelsOnOverload=true" to enable)
