reduce excessive capitalization in game options
Title case is meant for titles, headers, entity names, classes, keys, and button captions (see https://trac.wildfiregames.com/wiki/EnglishStyleGuide#Capitalization ). In the game options about every entry (two exceptions) in the lists is capitalized, which is both unnecessary and excessive. This patch removes title case from the listed items, reserving it for the section headers.
Test Plan: Check for mistakes.
