filter voters by "with comment" (illionas)
remove "vote now" etc. buttons watching (illionas)

until now, a user could know whether another user has already voted or not because the "vote now" button changed to "change vote". Due to a bug it showed this behaviour not for the logged in user but for the user being watched. This commit removes the buttons entirely when watching another user.
bugfix: display support of member

instead of wrongly displaying the support of the user when watching another member
new admin options
