.translate3d mixin needs -ms-transform property.

[psmak4]

Currently the .translate3d mixin looks like this:
.translate3d(@x, @y, @z) {
-webkit-transform: translate3d(@x, @y, @z);
-moz-transform: translate3d(@x, @y, @z);
-o-transform: translate3d(@x, @y, @z);
transform: translate3d(@x, @y, @z);
}

It needs the missing -ms prefix to look like this:
.translate3d(@x, @y, @z) {
-webkit-transform: translate3d(@x, @y, @z);
-moz-transform: translate3d(@x, @y, @z);
-o-transform: translate3d(@x, @y, @z);
-ms-transform: translate3d(@x, @y, @z);
transform: translate3d(@x, @y, @z);
}
