New lines are not handled properly in special attributes

[ccummings]

When there is a new line character in the value of a specialAttribute like style, the getValue helper does not strip the leading and trailing quotes because the regex fails. Specifically the .* in the regex only matches non-newline characters.

So a mustache template like this will not set the styles properly.

<div style="height: {{height}};
width: {{width}};"></div>

Fix is to strip out new lines so the second regex passes.

We could have changed the regex (.* to [^]*) to match across new lines, but this would pass a value with a new line to the special attribute setter which may not behave properly in some browsers.
