IA Pages - new description for the index page and specify the filter applied in the breadcrumbs

Action token requirement for link redirector is causing crashes.

Nix use of that and perform some basic referer checking. If there's a
failure, render an annoying interstitial page.

This is infinitely better than crashing.
ddgc_add_topic.pm - create script to add entries to the topics table
Don't bother encoding the URL, since there's only one parameter now.

I made a mistake when programming the migrated to thread redirect.
This rectifies it by moving the migrated check to after the exists /
ghosted check.

This also moves the thread -> idea migrated check to after the
permissions checks. There's no interface element exposed to migrate
non-general threads to IA ideas, but I think belts look smashing with
braces.

This adds calls for the new and old schemas and discards the result as a
workaround.
