inotify: Coding Style: name classes in lowercase.

inotify: dic.setdefault(k, d) ; v = dic[k] --> v = dic.setdefault(k, d) dict.setdefault sets a default value, but also returns the dict.get result. Getting the value on the next instruction was redundant.

inotify: make mask a class variable since it's instance-independant

inotify: RepoWatcher.updatestatus: document & use meaningful parameter names

inotify: server.walk(): use yield instead of for iterate on subdir when the directory is found, not once all the directories are found, since yield order doesn't matter

context: replace pseudo-set by real set
