Subject: [PATCH] Add `flushCompression` as an alias for `flush`

Supports use such as:

```javascript
// Not going to write again for a while.  If compression middleware is
// installed let's tell it to flush what we've got through to the client.
if (res.flushCompression) {
    res.flushCompression();
}
```

Currently the `res` object has a `flush` method regardless of whether
compression middleware is installed.  The built-in `flush` method issues a
noisy deprecation warning.  This patch provides an alias for the `flush`
method to allow detection of the compression middleware's `flush`.

This addresses https://github.com/expressjs/compression/issues/72.
