[stash-watcher] script broken by watchdog 5.0.0

[YonderboyLupus]

Starting with version 5.0.0 released last week, the watchdog library enforces passing keywords with keyword arguments:
https://github.com/gorakhargosh/watchdog/blob/master/changelog.rst#500

Now when the script is run with latest requirements an error is thrown by this line:
eventHandler = PatternMatchingEventHandler(patterns, None, False, True)

This could be fixed either by adding the appropriate keywords to each call to watchdog methods, or by pinning watchdog<5 (which worked for me). In any case, it would be good to pin the dependencies to known working versions to prevent it from breaking again in the future.

FYI:
Plugin FileMonitor is working with the new watchdog version, and (IMHO) it's easier to use and has more features than [stash-watcher].
