Onboard calls for nest and wink should use the same parameter structure

[busadave13]

Nest onboarder should use the same parameter structure as wink for the onboard parameters. Wink takes are array of objects while nest takes and object and string. Would be nice if there was some consistance

NEST
var params = 'client_id=' + authInfo[0].client_id;
params = params + '&code=' + authInfo[1];
params = params + '&client_secret=' + authInfo[0].client_secret;
params = params + '&grant_type=authorization_code';

WINK
ar postData = JSON.stringify({
'client_id': authInfo[1].client_id,
'client_secret': authInfo[1].client_secret,
'username': authInfo[0].username,
'password': authInfo[0].password,
'grant_type': 'password'
});
