documentation plugin fails when copying doxygen generated docs

Doxygen generates (by default) a folder "html" which contains ALL the html
and graphic assets in one directory. For my current documentation this is
approximately 3,000 files.

The current code in Xinc/Plugin/Repos/Documentation.php tries to shell out
and run "cp" via exec with a wildcard (*).. This however causes an argument
overflow in bash and the command fails (too many arguments error).

This code needs to be written to parse the directory listing manually via
"dir" and copy, or use a combination of find and xargs or tar.
