Game Update v6.4.0

This update corrects objective checks in Shiloh and Monocacy Junction and improves the main-menu news button. [*]Shiloh Pt. 1 now resolves its opening objective when the Union holds enough ground but has not inflicted the required losses. [*]Confederate victories in both Monocacy Junction missions resolve at the stated turn-22 deadline. [*]The main-menu news button opens this game's updates instead of its store page.
