Since Ceres is moving to using GitHub for issues, and the Google
Code URL in the current copyright header will soon become invalid,
update all the headers.

This replaces the broken CERES_VERSION and CERES_ABI_VERSION
defines with a different set, including integer versions for
MAJOR/MINOR/etc.
This also adds the Ceres version to Solver::FullReport().
