Support for a new site setting: `newuser_spam_host_threshold`. If a new user posts a link
to the same host enough tiles, they will not be able to post the same link again.

Additionally, the site will flag all their previous posts with links as spam and they will
be instantly hidden via the auto hide workflow.
FIX: Add unseen "*" icon on category list for new topics.
Updated client side Italian translation
Remove modal state to choose move type. Instead use two buttons on the multi select popup, one
for split and one for merge.
Support for "Select All / Deselect All" while selecting posts to merge / delete.
