(bug 23002) Imagelinks table not updated after imagemove. The actual bug was inconsistent behaviour between imagelinks and pagelinks for redirects.
* Parser now only adds the redirect source to imagelinks, like it does in pagelinks
* ImagePage now shows the file redirects in-line with the normal "The following pages link to this file:"
** Added message linkstoimage-redirect
** Removed the separate file redirects section and removed associated message redirectstofile
** ImagePage::imageLinks will first fetch image links to the file, determine which are redirects, and if there are fewer links than the limit, fetch the redirect target links.
