title: iCal4j and newlines
body: <p>I'm trying to read a calendar feed from <a href="http://meetup.com/" rel="noreferrer">http://meetup.com/</a>, but it seems that iCal4j is unable to deal with linebreaks in X-ORIGINAL-URL attributes: it fails on this line:</p>
  
  <pre><code>X-ORIGINAL-URL:http://www.meetup.com/chicagoscala/calendar/ical/The+Chicago
   -Area+Scala+Enthusiasts+(CASE)+Meetup+Group/
  </code></pre>
  
  <p>with this exception:</p>
  
  <pre><code>net.fortuna.ical4j.data.ParserException: Error at line 7: Illegal property [ -AREA+SCALA+ENTHUSIASTS+(CASE)+MEETUP+GROUP/]
      at net.fortuna.ical4j.data.CalendarParserImpl.parse(CalendarParserImpl.java:133)
      at net.fortuna.ical4j.data.CalendarBuilder.build(CalendarBuilder.java:174)
      at net.fortuna.ical4j.data.CalendarBuilder.build(CalendarBuilder.java:155)
  </code></pre>
  
  <p>I filed a bug for it, but I didn't get any response yet. Is this a known problem?</p>
  
  <p>BTW, this is a snippet of a hexdump of that file:</p>
