Permissions and Conditions should be linked in the documentation

I've had people ask me about this several times now, so I thought I'd mention it.

I keep getting people asking "can we restrict transitions to certain groups". This is after they've read and understood the documentation about the permission schemes - they actually need to be looking at conditions on workflow.

I don't think the conditions section needs moving, but it would be logical to have a pointer to it on the permission scheme pages.
