Title: Add transform/transform-origin mixins and fill out transition mixins with non-shorthand methods

Also, I updated the transition mixin to allow for transform as a property to be transitioned without the duplication. For example, this was what I wanted to generate:

```css
.myClass {
-webkit-transition-property: -webkit-transform, opacity;
-moz-transition-property: -moz-transform, opacity;
/* and so on */
}
```

Which is now possible thus:

.myClass {
.transition-property(e("transform, opacity"));
}
