v6 full / v13 demo - making things easier

This update is mainly focused on making various things (like replaying and seeing objectives) easier. [h3]Progress control[/h3] [list] [*]Added a feature to allow resetting the unfinished missions to the initial state, which allows replaying the game without losing access to missions. [*]It is possible to reset the unfinished missions including videos and tutorials (for the full experience) or only reset the missions (for speedrunning). [*]It is also possible to restore the finished missions to everything that has been unlocked. [*]The feature can be found at "Options/Game/Progress control". [*]Please note that replaying missions currently not unlocked from other lists will still change the point count for the unlocked missions list! [/list] [h3]Various[/h3] [list] [*]Added a "Show objectives" feature in mission preview. [*]Slightly increased the visibility of a light switch in one of the first extraction missions. [*]Added the ability to move while aiming. [*]Added automatic night vision control (can be disabled by turning off the "Options/Game/Enable auto night vision" setting). [/list]
