Temporary htmlpurifier filter added - to be removed when SafeIframe option is available.

By turning 'HTML.SafeEmbed' and 'HTML.SafeObject' ON, we can avoid
having to write and maintain all kinds of filters.

I have deleted all of the filters that are no longer necessary.

Unfortunately, we have to keep two around, Skype and Twitter,
since their embed code includes Javascript.
