Static map - can only generate a single style

[rayshan]

Hi,

1.0.1

Params with a single style object:

var params = {
    center: '44.9545,-93.3365',
    zoom: 10,
    size: '640x640',
    scale: 2,
    maptype: 'roadmap',
    style: [
        {
            feature: 'all',
            rules: {
                invert_lightness: true,
                hue: '0x57574e'
            }
        }
    ]
}

Correctly generates:

https://maps.googleapis.com/maps/api/staticmap?center=44.9545%2C-93.3365&zoom=10&size=640x640&scale=2&maptype=roadmap&style=feature%3Aall%7Cinvert_lightness%3Atrue%7Chue%3A0x57574e&key=xyz

But when there are multiple style objects:

var params = {
    center: '44.9545,-93.3365',
    zoom: 10,
    size: '640x640',
    scale: 2,
    maptype: 'roadmap',
    style: [
        {
            feature: 'all',
            rules: {
                invert_lightness: true,
                hue: '0x57574e'
            }
        },
        {
            feature: 'road.highway',
            rules: {
                visibility: "simplified"
            }
        }
    ]
}

Generated URI is missing &style=: https://maps.googleapis.com/maps/api/staticmap?center=44.9545%2C-93.3365&zoom=10&size=640x640&scale=2&maptype=roadmap&style=feature%3Aall%7Cinvert_lightness%3Atrue%7Chue%3A0x57574e%7Cfeature%3Aroad.highway%7Cvisibility%3Asimplified&key=xyz

Expected: https://maps.googleapis.com/maps/api/staticmap?center=44.9545%2C-93.3365&zoom=10&size=640x640&scale=2&maptype=roadmap&style=feature%3Aall%7Cinvert_lightness%3Atrue%7Chue%3A0x57574e%7C&style=feature%3Aroad.highway%7Cvisibility%3Asimplified&key=xyz

The test is also missing &style=: https://github.com/moshen/node-googlemaps/blob/master/test/unit/utils/parseStylesTest.js#L48
