Support for sorting numbers

[iamdevman]

Added support for sorting numbers.

It already supports sorting by numbers. See example here http://apuchkov.com/knockout-orderable/examples/basic.html
Can you tell which specific use case you are trying to solve with this?
Thanks

It does in fact support number sorting, but not in all cases. As i can see, it sorts numbers "alphabetically". Meaning that all numbers starting with 9 will be before numbers starting with 8 etc.... depending on the sort order.

However, this has an issue when it comes to larger numbers such as my case (see image, column is sorted in descending order) :

As you can see, the number 973676 should be out in first, before 99344, hence my comment on alphabetical ordering.

And the code I committed will do a sort based on Numerical order, not alphabetical.

Latest version sorts numbers correctly, see here http://jsfiddle.net/bqJZC/

Don't think i was specific enough. Here is my case : http://jsfiddle.net/bqJZC/1/

Anyway, i've added the support for that case in my version of the code. Basically it just tries to parse into integer & adds support for undefined values.

I see you store numbers as stings in your ViewModel, this is why it works differently. Will review your change and merge them in a bit later.
Thanks
