Simply adds the total amount of loot that can be secured to the escape van secured loot text.
If you are missing a dollar, don't worry, that's just dollar dragon taking his tax (Sometimes the secured value gets truncated so it will be -1 of the total loot value)
IF YOU ARE UPDATING FROM 1.0.0, PLEASE REMOVE THE "z_TotalMissionValue-300_P" FILES FROM YOUR MODS FOLDER
Currently, the briefcase mission just shows a random value, so don't run around looking for all the loot like I do xD
Also some missions may show the wrong total mission value. I am currently working on a fix / changing the way of getting the loot values and will be updating the mod soon :)
