[Building Sakai] new web content tool error

Wed Jul 30 16:59:15 PDT 2014

In this ticket:
https://jira.sakaiproject.org/browse/SAK-18721

There was a one line fix to simply replace spaces with %20 so that the URL
stored is correct. On retrieval, this can be added as well so that URLs are
always correct, even if added in some other manner other than the UI.
