implemented sortable inline functionality

questions. there is no css other than the bootstrap css, so i'm not
sure where I should put css that's necessary as part of the sortable
inlines.

also included is js/jquery.sortable.js. this is a super lightweight
sortable implementation
removed an unnessary comment
Refactor due to feedback.

Created django_admin_bootstrapped.admin module for admin models. Created SortableInline mixin that adds the sortable javascript as wells as css for the sortables.

usage invoked in admin.py as follows
```
class MyInline(admin.TabularInline, SortableInline):
    # override sortable_field_name if it is not a position field on the model

Feature/sortable inlines
wrapped the inlines inside well to provide a better feedback, useful if using sortable inlines
updated README, added LICENSE, version bump
updated CHANGELOG
added collapse_stacked option to SortableInline mixin to allow for disabling the collapse of the inlinse
created CollapsibleInline mixin that allows the stacked inline to be collapsed by setting the start_collapsed variable to True. By default stacked inlines are not collapsed. Also the stacked.html template has been changed to reflect the var name.
