New syntax for export block in Org 9

[oylenshpeegul]

It looks like #+BEGIN_HTML should be #+BEGIN_EXPORT html now.

Without this, <script> gets changed to <script> and so forth, so the javascript does not work.

Thanks for this. I ran into this problem just now, trying org-html-slideshow for the first time. It's nice to be able to find the solution quickly. I confirm that it works.

My guess is that it would be easier for @stuartsierra to accept this PR if you specified that this syntax is for OrgMode >= 9.0 only.

Cheers, and thanks again!

You may want to refer to the fork https://github.com/aiba/org-html-slideshow. It fixes an important conflict with new versions of Chrome that prevented Presenter View slides from correctly tracking when slides were advanced, as well as the export syntax you mentioned.
