Title: [core] Change Y.require() to a similar signature to Y.use()

This change gets rid of the multiple parameter signature which could potentially result in unexpected behavior based on certain modules being replace with the `Y`. This is the new signature:

```js
YUI().require('es6-set', 'es6-bar', function (Y, imports) {
var Set = imports['es6-set']['default'],
set = new Set();
});
```

I fixed the coverage tests and we have 100% coverage over the `require` function (still low for the rest of `yui-base`):
