We currently use client-side storage to keep track of what revisions and
posts have already been thanked for. This is problematic because client-
side storage is not permanent, making it easy to send duplicate thanks
if you have logged out and in, or switched computers.
This starts storing new thanks in the log_search table, which is
designed for efficient querying of metadata associated with a specific
log entry. With this, we can easily check to see if a user has already
sent thanks for a specific revision.
The UX is a bit weird right now, we only check log_search when actually
sending thanks again, in which case the user thinks they have sent
thanks again, but no duplicate thanks is actually sent.

MediaWiki core change I04b1a384 added support for i18n of API module
help. This takes advantage of that while still maintaining backwards
compatibility with earlier versions of MediaWiki.
Once support for MediaWiki before 1.25 is dropped, the methods marked
deprecated in this patch may be removed.
