Add overload to select(...)

Select supports these 2 syntax:

```
qb.select('s.id, s.title, s.artist, s.genre')
```
and
```
qb.select(['s.id', 's.title', 's.artist', 's.genre'])
```

but I constantly find myself doing this:
```
qb.select('s.id', 's.title', 's.artist', 's.genre')
```

Can we also allow the vararg approach?
