Detached Head issue *fixed*

I was trying to commit changes, but the internet was unstable. Just
before the commit finished uploading, the connection cut out and I got a
detached head notice. I continued to make changes. I just fixed it:
-acceleration will be a simple velocity equation
-added an icon for the program (not working, yet)
-added the exit button to the form (still need to use the correct image
files)
-changed the actual code (as opposed to simply the layout)
