Jeremy Stanley 98ed431f6c Convert Arcana files from DOS to UNIX line endings
Switch all the Arcana text/HTML/CSS/JS files which used CR+LF line
endings to plain LF like other files in the repository, for
consistency and ease of maintenance. Some files had mixed line
endings, so fix them as well. Also clean up a handful of mixed
tab+space indents in www/index.html along with one line which had
only whitespace characters on it.

This change makes no edits to file content other than whitespace.
