Updating doxygen documentation.

Added mechanism to document API changes in the generated doxygen
documentation. Developers are now expected to keep MajorAPIChanges.md
file updated as they change APIs or major design features.

This change now requires doxygen 1.8 or greater since we now rely on
markdown support in doxygen.
