More granularity in permissions

[Number8]

Perhaps I am overlooking something, but in OG 1.3.1 it appears anyone with read/write privileges can delete any object.

I would like delete permission to be separate from read and write. 

The Revisions feature in Documents is great, but it is somewhat undone if any editor can delete documents or revisions.

Yep, will take it into account for 1.5. I think too that there should be a separate permission for deletion.
