[FEATURE] Continue Game where I last left off

[oddible]

One thing which would make re-launching the game more enjoyable would be an option to just pick up where I left off. I always launch into the Boot Camp campaign on the map, then have to go hunting around in the load screen for the file I last played, better to:

1) At minimum, launch me into the last campaign I played
2) Provide a 'Continue' button which basically performs a Load Last Save that offers to pick up where I left off.
