Title: Added optional support for duplicate keys

Added support for duplicate keys via ALLOW_DUPLICATE_KEYS constant. Will take something like:

```javascript
{
"a" : 1234,
"a" : 4567,
"a" : 8910
}

and convert to

{
"a" : 1234,
"a.1" : 4567,
"a.2" : 8910
}
```

In this way, if someone has a JSON file with keys that are acted like verbs, for example, for using JSON as configuration files, where you may have multiple action blocks. Rather than wrap blocks in extra brackets, or be forced to add unique charachters to verb.
