Simply adds the total amount of loot that can be secured to the escape van secured loot text.

I have only been able to do some light testing but it seems to work as intended.
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)

I have been notified that 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 :)
