Turn an HTML HREF reference into an absolute path.  This will locate files based upon 
relative references, specialized help system references (i.e., help/topics/...),  and 
absolute URLs.

@param sourceFile the reference's source file
@param ref the reference text
@return an absolute path; null if the URI is remote
@throws URISyntaxException if there is an exception creating a URL/URI for the image location
