In some places we prevented cache poisoning, in others we did not. We
also did not place any restriction on the minimum value for a revision.
This change introduces a new set of functions for configonly endpoints
which validates the revision numbers passed in. If the revision is
either too old, or too new, it is rejected and the file content is not
cached. The content is still served, but caching headers are not sent,
and any local storage caching is prevented.
The current time is used as the maximum version, with 60 seconds added
to allow for any clock skew between cluster nodes. Previously some
locations used one hour, but there should never be such a large clock
skew on a correctly configured system.

TinyMCE uses a magic langstring only present in RTL languages which
makes it hard to automatically fetch from their strings.
Since it's the only magic string I can find a reference to (after
searching their codebase), I've elected to add this in the lang.php
serving layer. This allows us to use our own langstring instead of
re-declaring something that should be stored once across Moodle.

Add support for translation of the TinyMCE interface.
TinyMCE translates English language strings rather than keys, and a tool
to perform this translation is included.
