[FIX] Survey: typo (en_US wording)
[FIX] website_forum: fixed comment unlink action :
- fixed call to a wrong method
- fixed button display, now based on the standard way of managing karma (popup when
not having the required karma)
- fixed button display karma computation
- some css tweaking for this button
[FIX] website_event: pager now takes into account the searches performed
by the user. Otherwise it was resetting the search to all events.
