Removed obsolete files.

This includes the Counter interface, which was replaced by TextOutput and
the original implementation of the Counters package. These files were in the
RCS "attic" at the time of the transition to git.
Initial implementation of the interfaces below:

    Identity
    Leadership
    Morale
    SprayingFire
    Status

These are not actually applied to any of the existing classes (yet).
Minor changes/fixes to comments, primarily affecting spacing and links.
Initial implementation of the Mobility and Portability interfaces.
Updated to work with doxygen 1.8.2
Added entry to support links to enum elements.
Added another entry to support links to enum definitions.
