Tyler Veness 3cd1253977 artf2612: Update license in source files.
Years update, references to WIND_BASE were removed, and WPILib license was
moved to the root directory of the project.

If there was already a comment block, a year range through 2016 was created
using the first year in the comment. If there was no comment block, a block
with just the year 2016 was added.

Comments were not added to files from external sources (NI, CTRE).
