[rfc] [icedtea-web] desktop icon is pointing to cache instead to real url

[Jiri Vanek]

Hi!
During digging in desktop subsystem of ITW i found that desktop icon is pointing to cache instead to 
url. HAve anybody idea why??? Eg it will not survive -Xclearcache,..

This simple patch should fix it to point to real url instead of cached version:

          //Shortcut executes the jnlp from cache and system preferred java..
-        fileContents += "Exec=" + "javaws" + " \"" + cacheFile.getAbsolutePath() + "\"\n";
+        fileContents += "Exec=" + "javaws" + " \"" + file.getSourceLocation() + "\"\n";

          return new StringReader(fileContents);
