UI and Achievement Update

The achievement system has been updated so that your progress towards certain achievements are kept track of and displayed on the achievements page. Now, due to a mistake while configuring and testing the achievements to this new system, I had to reset a lot of the achievements. I'm hoping that this doesn't happen again.

The settings screen has been given an overhaul and now separates the settings into tabbed pages. There are also new settings that have been added but are currently non-functional. These are: Axis assignments, sounds in space, graphics settings, and the Workshop tab.

• I did discover that my attempt to prevent crashes on loading quicksaves did not work. I have not been able to fix that bug yet.
  
• I still don't know how to program the command module AI to try to stay in orbit. So be careful not to de-orbit it.
  
• For some reason, the Apply button is enabled when you go to the settings screen. Haven't traced that down yet.

• Periapsis and Apoapsis indicators on the HUD
  
• Time Acceleration
  
• Workshop (eg: for user-made scenarios/story lines)
