FuzzyMatch query param missing from forwardGeocode

Nobody has claimed this yet.

i was trying to use the FuzzyMatch param from the API docs today, & i got the error the fuzzyMatch keys isn't valid, so i went & check the geocoding.js file & yeah fuzzyMatch isn't here

```
Geocoding.forwardGeocode = function(config) {
v.assertShape({
query: v.required(v.string),
mode: v.oneOf('mapbox.places', 'mapbox.places-permanent'),
countries: v.arrayOf(v.string),
proximity: v.coordinates,
types: v.arrayOf(v.oneOf(featureTypes)),
autocomplete: v.boolean,
bbox: v.arrayOf(v.number),
limit: v.number,
language: v.arrayOf(v.string)
})(config);

config.mode = config.mode || 'mapbox.places';

var query = stringifyBooleans(
xtend(
{ country: config.countries },
pick(config, [
'proximity',
'types',
'autocomplete',
'bbox',
'limit',
'language'
])
)
);
```

Start in geocoding.js at Geocoding.forwardGeocode, reviewing both the config validation and the query parameter selection shown in the issue. Confirm that fuzzyMatch is accepted and forwarded to the API, then verify the resulting request behavior with the repository's relevant geocoding checks.
