The patch adds ability to filter the list of token by the token value,
the user and the service. Also the button to create a new token is made
more prominent and easier to spot.
I suppose the original reasoning was that the web services protocols are
pluggable and that plugins can provide external function. But those are
not good reasons to put the whole Web services section under plugins.
Web services are not a plugin type and they always felt very
counter-intuitive there.
From the server administrtaion perspective, web services are similar to
scheduled tasks and therefore, they should live in the same section.
