[wicked] Problem with embedded images (patch)

[Adam Yearout]

While playing around with the sample wiki page provided with Text_Wiki, 
I noticed that embedded images weren't working properly.  I was able to 
track it down to wicked/lib/Text_Wiki/url.php.  The class extension here 
breaks the URLs for embedded images by turning them into Horde external 
links.  I took existing code from Text_Wiki's url.php and applied it 
here so that URLs are only translated if they are not images.
