rss_converter_twitter.com.xsl: cleanup titles

Prepend a white space in front of some URLs (those not preceded by an
open parenthesis) because otherwise they get rendered attached to the
preceding text.

Also strip non-breaking spaces and horizontal ellipses, they are not
needed because the RSS feed show the full URLs.
