New level and lots of changes

There's a lot of new things in this update. I've made a new level, called Beachside. It's a coastal map with a new resource to transport - pineapples. I will make them deteriorate over time, therefore losing value in the next update. This will give you a bit more of a challenge (should I go faster to get more money per pineapple or should I go slower so I don't lose any pineapples?). 

I've added a split/merge rail piece. Just use 'A' or 'D' to choose your direction when approaching a split rail. I've made the camera transitions smooth instead of just jumping to the position to make it feel less disorienting.

I've changed the upgrades so that you can customise individual carriages. You can buy lids, upgrade the stability of the containers and the strength of the lids. Use left shift to open the container lids.

The last big change is the UI. I've added a bit of personality to the menus and buttons.
