Negative values inside of css properties.

[ghost]

I'm trying to sanitize property with negative value, but it removes the property,
i've attached the failing test

class IntegrationTestCssNegative < Loofah::TestCase
    def test_css_negative_value_sanitization
        html = "<span style=\"word-spacing: -1px;\"></span>"
        sane = Nokogiri::HTML(Loofah.scrub_fragment(html, :escape).to_xml)
        assert_match %r/-1px/,    sane.inner_html
    end
end

I believed this was fixed on master (see ca618fc) but this test case fails. Will try to figure it out today.

Ah - OK. The general problem of negative values is solved on master (and I added your mostly-unmodified test case to make sure). But the word-spacing property isn't whitelisted.

I've opened #68 for the whitelist problem. And so I'm closing this issue.

Thanks!

Got it, Thanks Mike!
