Currently, the 'Watchlist notification delay' is part of the 'Site options'. However, it would be better to keep it in a configuration screen in the 'Plugin administration' for this plugin, similarly to the forum post delay.
Test instructions (They are written with the new categorisation introduced in https://reviews.mahara.org/#/c/10810/):
1. Go to 'Admin menu' -> 'Configure site' -> 'Site options' -> Open the panel 'Site settings'.
Expected result: The 'Watchlist notification delay' setting is not there any more.
2. Go to 'Admin menu' -> 'Extensions -> 'Plugin administration.
3. Navigate to 'watchlist' plugin under 'Plugin type: blocktype'.
Expected result: There is now a configuration button with the alternative text 'Configuration for blocktype watchlist'.
4. Click the configuration button.
Expected result: The delay notification field is there an a numerical value can be entered as per the description.
