Realistic Lifespans (0.2a)

Re-upload of Realistic Lifespans. Fixed some game-breaking bugs. Premise is simple, 1 year = 4 in-game days. Modified lifespans to be proportional to an average lifespan globally (around 75 years). Infant: 8 Days Toddler: 12 Days Child: 16 Days Pre-Teen: 16 Days Teenager: 20 Days Young Adult: 88 Days Adult: 100 Days Elder: 40 Days. Additionally, added two new length options, Lengthened (2x) and Week-Long (1.75x).
