Title: Faster Y.merge()

This change speeds up Y.merge() 10 to 40% (depending on the browser) by moving the merge logic inline instead of calling out to Y.mix().

### Running Locally

The built yui modules are intentionally not included in order to keep the diffs clean. Before testing this change, you'll need to build them:

```bash
$ cd src/yui && ant all
```
