ExCSS 4.3.0 does not properly parse transition CSS #184

Hello,

I have the following CSS:

* {
    transition-property: background-color, color, border-color;
    transition-duration: 0.5s;
    transition-timing-function: ease;
}

The transition-duration and transition-timing-function work fine, but the transition-property declaration is not parsed by ExCSS' StylesheetParser.Parse method.
