Update 1.2.2 - Delivery bonuses and UX improvements

While working on UX improvements, I felt like the game was getting sluggish after some progress, so I decided to add an incremental delivery bonus. Basically every completed delivery adds a 5% reward bonus to every future delivery. As you complete more deliveries, you get extra bonus.

Additional things covered in 1.2.2:

• The delivery selection buttons now cover the whole width of the checkpoint menu. There's no longer a weird jump straight to performance upgrades when going up with a controller.
• Added a controller navigation warp to the settings menu and the main menu.
• Fixed some buttons staying in focused mode after being pressed with a mouse.
• Fixed a bug where starting a game in an ice wastelands biome doesn't give the discovery goal.
