[0.2.1.0] New uploader and bugfixes

[0.2.1.0] FULL RELEASE

- The score and shadow upload is now significantly more intelligent
- Uploads are now done on a separate thread, so you can continue playing while your score and shadow is being uploaded in the background
- Instead of a "Connecting to server" text that took up a lot of screen there is now just a spinner animation to let you know something is happening in the background
- The game will prevent you from quitting for the first 5 seconds while it's trying to upload.
- It is highly advised you DO NOT turn off the game while that spinner is on screen, as you might loose your scores.
- Fixed an issue where players would randomly loose a life, or their whole run, for no reason
- Fixed a graphical bug where you would see a black spot somewhere in the distance after jumping
- Got the cameras (all of them) to function as I wanted and expected them to function, fixing as many bugs as i could find
- All cameras now rotate with the ship when the ship is on a upside-down road
- Re-enabled the old shield mechanic that would bounce your ship when you fall in the pit, however the bounce behaves exactly the same EVERY time (same height, same speed) when you bounce, which was always the intended behaviour but I finally figured out what was broken with it.
- Fix for first person camera not twisting with the ship sometimes when on the skyways
- Ship has been tweaked to feel less sluggish, hopefully.
- Speed in HardCore has been set back to the previous value, it was a bug that it was so slow
- the seed that was last typed in gets remembered between game sessions
- Fixed the issue with shadows not uploading correctly when in MP
- Fixed a different issue where scores were not being uploaded
- Fixed a problem with the scores being uploaded
