Adjusted query string array representation to remove indices.

Hi guys - after some discussion about the implementation provided in PR #8261, it looks like we should adjust the implemented array handling a bit. Right now arrays are encoded with indices like:

some_array[0]=value1&some_array[1]=value2&some_array[2]=value3

While this implementation is somewhat supported by external languages and frameworks, it's not as well supported (by default) as the following query string representation for arrays:

some_array[]=value1&some_array[]=value2&some_array[]=value3

For example, PHP and Rails both expect no indices for arrays.

This PR adjusts the url package to make sure query string encoded arrays do not include indices. Thanks!

Could you also increment the version in package.js as you see fit?

Shoot - sure thing @benjamn, thanks!
