Resolve symbolic links just as KTextEditor
Review Request #129792 - Created Jan. 8, 2017 and submitted
KTextEditor::openUrl() resolves any symbolic links but KateDocManager::findDocument() does not. This means that every time you open a symlink Kate believs it is a new file, but you end up with the same url as the previously opened one. This patch adds resolving of symlinks also to KateDocManager::findDocument(). Another option would be to stop resolving symlinks in KTextEditor, but that is a behaviour change.
Opening the same symlink many times does not create multiple document instances of the same file.
