#262 Fixes, daddies and no twinges

• Fix: BC shot not counting down when on the pill at the same time and pill being considered the main contraception method
• Fix: npc reaction about pregnancy causing blank screen
• Change: contraception disqualifying potential fathers. If there's a baby, somebody's got to be the father
• Change: commented out the twinge message which gives 100% spoiler about pregnancy before we could possibly know about it

Added after original request

Fix: corrected journal displaying up to 2 unborn kids after you already had 2+ children born.
