refs #1205
List of spaces at home as list, but in the profile as thumbnails

With bf4967c0c36f we changed the list of spaces in the user's home to be
a list instead of thumbnails, but it ended up changing the spaces in the
user's profile as well.
Reverted the spaces in the profile back to thumbnails.
