Sam Clegg 63860617b3 Add copyright information to .py files
This change adds explicit copyright information too python
files files.  The copyright year used in each case is the
date of the first git commit of each file.

The goal is to allow jsoncpp to be integrated into the
chromium source tree which requires license information in
each source file.
