Fix #297 -- Add Django admin' inline formset support

[mardukbp]

As described in #249 and #297 django-select2 does not currently work with selects added dynamically in the Django admin.

The solution was implemented in #249 and all credit should go to Jurrian Tromp. I only added a small correction:

- jqRow.find('.select2-container').remove()
+ jqRow.find('.django-select2').parent().find('.select2-container').remove()

to only remove .select2-container when it is a sibling of .django-select2. Otherwise the wrong .select2-container might get deleted.

@codingjoe the above code looks good to go, wondering when can it be reviewed and merged as a couple of my prod websites are affected, could wait a couple days before i create a fork myself and use that in my repos

I left a comment. Once it's resolved I am happy to release this.

Thanks for your suggestion @codingjoe. I tested it with my Django project and everything works. I apologize for taking so long to update my PR.
