Since !10143 (merged) prepped all the text, might as actually turn it on. Broadens slave generation parameters in REC Runaway Cat, so that it might be a catboy, or a slightly younger catgirl, if your game settings permit (would have relaxed maximumAge too but the text does describe her as "young"). Fixes wording on the sale option since you're pretty clearly returning her to her original owner, not selling her on the open market.
Also adds some contextualIntro to PE Headgirl Concubine since apparently that was already in my commit queue.
