Title: roll back <*> as infix of ap

see https://groups.google.com/forum/#!topic/scalaz/g0YPdgBeEAw

### steps

```scala
scala> 9.some <*> {(_: Int) + 3}.some
res20: Option[(Int, Int => Int)] = Some((9,))
```

### what this changes

I am rolling <*> back as infix `ap`.

```scala
scala> 9.some <*> {(_: Int) + 3}.some
res0: Option[Int] = Some(12)
```
