Title: explicity interpolate the variable

in sass 3.4, this scss:

```scss
@include keyframesNew('myanimation') {
0% {
opacity: 1;
}
100% {
opacity: 0;
}
}
```
with the non-interpolated variable name results in:

```css
@keyframes $name {
0% {
opacity: 0;
}
100% {
opacity: 0;
}
}
etc
```

In 3.3 and 3.4, interpolating results in:

```css
@keyframes myanimation {
0% {
opacity: 1;
}
100% {
opacity: 0;
}
}
etc
```
