fix(forms): ensure select2 is included last

Select2 needs to be initialised AFTER jQuery is added to the global namespace.

This commit also:
- Ensures min-width for the select2 widget, and explicitly initialised the widget
for the first field selected.
- Add latest django context_processors to TEMPLATES.OPTIONS setting

 -  simplejson == 3.6.5
 
+*NOTE*: While the latest Django 1.5.X is supported, the bundled jQuery it includes is outdated (1.4.2) and as such, most of our admin frontend scripts fail. This means that to use advanced-filters in Django 1.5 admin, you'd have to probably include your own jQuery (1.9 or later) and add it to global namespace prior to other scripts in `AdvancedFilterForm.Meta`.
