#17 Folder Item(s) Display

[Michael Glazer]

Two issues that are noticable:

1. Binary data size is not displayed.

2. The date added / date_modified on sort is kinda
funky. Mak sure on new Object we add both date
values to each property for all Object types.

A easy resolve might be to finally move the
read/view/browse folder item(s) method to the folder
Object_admin itself instead of the global 'manage' core
class.
