Improve default crud look and feel

The admin skin in frameworks such as django or synfony is much more polished than the play! one.

Automatic admin is a great feature and it is important to have a polished official skin that one can give to the end administrators (in my use cases they are almost end user) with little or no modifications, actually default crud skin is not really suitable for non programmers please take a look to the default django admin ui, to the synfony one or to projects such as django-grappelli (http://code.google.com/p/django-grappelli/wiki/screenshots)

thanks
