[HTML][PATCH] use 'class' instead of 'align' for caption

[HTML][PATCH] use 'class' instead of 'align' for caption

Hello,
I prepared a small patch to make ox-html use 'class' attribute instead
of 'align' in caption element when it is used in tables.

The reason is simple, according to xhtml1 Strict specification 'caption'
element doesn't have 'align' attribute, this is true for HTML5 too.
Instead of 'align' attribute it is more cleanly to use 'class' attribute
and to add corresponding entries to CSS.

In included patch I didn't add word TINYCHANGE because I don't is it
small or not (I don't understand what exactly the phrase
> your total contribution (all patches you submit) should change less than
> 15 lines
means, how lines are counted).

I applied this patch.

I checked http://orgmode.org/worg/org-contribute.html to hastily and
thought you already signed the FSF papers.

So I added a TINYCHANGE to your commit message.

You cannot submit new patches until you sign the FSF papers.
Thanks for considering this -- and let me know how I can help.

Best,
