Feature: Preserve position of elements

[amitguptagwl]

For some processing purpose, it is requied to preserve the position of tags and text value of a tag. Eg

<store> locates in
        <region>US</region>
         and
        <region>Japan</region>
        only
</store>

currently parsed to following when arrayMode is true.

{
    "store": [
        {
            "#text": "locates inandonly",
            "region": [
                "US",
                "Japan"
            ]
        }
    ]
}

The expected output is one of the following

{
    "store": [
        { "#text": "locates in" },
        { "region": "US" },
        { "#text": "and" },
        { "region": "Japan" },
        { "#text": "only" }
    ]
}

{
    "store": [
        "locates in",
        { "region": "US" },
        "and",
        { "region": "Japan" },
        "only"
    ]
}

As you can see, I added a pull request that adds this behavior. One thing I did not yet tackle was handling of CDATA blocks in text.
