Remove "not allowed" when supporting comments

Hovering over the votes showed a "participation not allowed" message
which was annoying when scrolling with the browser or simply moving the
mouse around the page. Furthermore, it hid the information about the
number of votes, links to show/collapse replies, ...

We're planning to change the behavior of all the "participation not
allowed" messages in order to show them on click instead of showing them
on hover (just like it's done on touchscreens). In the case of comments,
supports, however, there's very limited space in the part showing the
number of supports for comments, so adding this message without breaking
the layout is challenging.

So, for now, we're simply redirecting unauthenticated users to the login
page. If find an easy way to implement a better user interface in the
future to display the "participation not allowed" message, we might
change this behaviour.
