[uf-new] acessibility problem with currency microformats

[Alexandre Van de Sande]

it looks like again the currency is using a already documented acessibility
problem of abusing the abbr tag.

this costs <div class="money">
			<abbr class="currency" title="USD">
				<span class="amount">42.67</span>
			</abbr>
		</div>
	


The semantic correct way that a screen reader should read this, according to
the specification of waht abbr stands for wil be:
-this costs U.S.D.


screen readers are taught to , when encoutering and abbr, to read the title
instead of the content, that's why abbr was created. This already happens in
other microformats and is an error. I see no good reason not to use a <span>
instead.
