move inBounds() method from LazarusBlip to superclass Blip. Add properties alive, active and visible to Blip.
MinimalistBoard now skips update and drawing Blips based on their active and visible values.
prettier colors :P
preempted a bug where Blips would be drawn on the same turn that alive flag is switched off
Introducing... DeathBlip! Added kill() method to Blip in preparation.
blip.visible check was reversed
Blip turns gray upon kill(). DeathBlipTest implemented.
LazarusBlip now resurrects from kill() in addition to offscreen "death"
Fixed a bug where color of Blip was permanently stuck at grey even after revival
