Added templates for 'funny' widgets here: django/conf/admin_templates/widget

Browse Source 
Added a follow argument to manipulators. This allows you to exclude/include fields and related objects ( recursively), defaulting to current behaviour, meaning that forms can modify a subset of fields. This should fix #445. Fixed update generic view to use this (will change others soon).  Merged to trunk r772.
