Improve in-game tutorial

[Cervator]

Currently the in-game tutorial remains pretty much unchanged from when we adopted the game years ago. There are some things we could probably explain a little better even from those days, and maybe new stuff we added - thoughts?

• Have the player accelerate and note how the camera zooms out to show more area
• Have the player change into a new ship and highlight how there are both light and heavy weapon pods and how ships may vary (some new players have spent all their money on a new ship only to realize they have no weapons that'll equip nor money left to buy any)
• Show how to acquire and use mercenaries including how they (and everything else, really) will pick up nearby loot - but at least with your mercs you can access their inventory and take it back, I think? Not the money though, but equipment?
