Added author information to all HAL components where it was missing

Also consolidated identical names into the consistent capitalisation.

The component author was found either using git history or copyright header
in the file.  I only used the name, not email addresses, because I do not
know if people want to have their email address exposed in the LinuxCNC
manual pages, nor if any email address I could find is up to date and still
relevant.
