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). Change-Id: Iff4f098ab908b90b8d929902dea903de2f596acc
