CSS parser: Add error recovery while parsing @-webkit-keyframes key values.
<http://webkit.org/b/115175>

Source/WebCore:

From Blink r148714 by <apavlov@chromium.org>:

If not a percentage, "from", or "to" value is used in a key list, the rule is erroneous,
and due to the absense of recovery, the parser skips the following, valid CSS rule.

On a related note, keyframes, whose selectors contain invalid keys, should be discarded
altogether, according to <http://www.w3.org/TR/css3-animations/#keyframes>
