xhtmls image align needs fix

[GoogleCodeExporter]

In r971 there's a fix for the image align in XHTML target (with --css-sugar).

But the fix needs a fix :)

You can't use display:block because it breaks the paragraph. Left/right aligned 
images are also used inside paragraphs, like this:

    [left.png] my text here [right.png]

The correct attributes for these two are:

    style="float: left;"

    style="float: right;"
