Textile justified or centered header not parsed

[kpym]

In textile we can center à header with

h1=. Test

that should produce the following HTML

<h1 style="text-align:center">Test</h1>

but pandoc transpile it to

<p>h1=. Test</p>

In a similar way we can justify (h1<>.) and right align (h1>.).

It would not be hard to make pandoc add a style attribute in this case, but this would only affect HTML output; you wouldn't get proper behavior in e.g. PDF output. Still, this would be better than emitting a = character!
