terrain2wiki: Remove leading/trailing whitespace in lines before parsing

The Dark Flagstones terrain had .aliasof at the last line before the
closing tag, which caused a newline to be output right before </code> in
the wiki page, and in turn causing MW to generate invalid XHTML.

This change makes the generated wiki page valid XHTML again (except for
another problem with the actual glamdrol theme, not the page contents).
