Smoothie Edge-0b3e620 and later now pays attention to config option "planner_queue_size".

After updating to this or later versions it may be necessary to configure the planner_queue_size to 32. The previous default in the config files was 64.

Background: With a setting of 64 smoothie has been observed to crash (halted printer movement and become unresponsive to controls) mid print. This was on a smoothie with the planner_queue_size of 64 while also configured for the kossel arm solution.
