inotify: Clarify the use of "watcher" name. Currently, Watcher is a class in inotify.linux.watcher, but it's also a class in inotify.server . To complicate things further more, the latter has a 'watcher' attribute, an instance of the former class. When it comes to the 'watcher' attribute of the Server class in inotify.server, one can get quite confused: is it a Watcher object from inotify.server, or from inotify.linux.watcher? Changes: * in inotify.linux.watcher : nothing * in inotify.server : ** Watcher class is renamed to RepoWatcher ** server.watcher is renamed to server.repowatcher
