Legacy SearchEngine class really has three roles: 1. Manage search plugins, 2. Handle the search job, and 3. Handle the download of the torrent file using the search plugin. Now it is splitted into 3 classes: SearchManager, SearchHandler and SearchDownloadHandler. Search GUI is also improved.adaptive-webui-19844
