Add new features to ensure we do not lose functionality from what was…

[SharonStrats]

The reason for this work is that in testing, a couple of things were discovered.

1. The Dokeili planners are resource-oriented and do not fully express SolidOS container semantics. In particular, acl:default is not copied over from the inherited access when granting access to a container.
2. This discovery also led to the realization of the complexity of the container access control and that the current design missed some functionality. One of the biggest is that for a container there are actually 3 "types" of access that can be granted because of the acl:default. Access to a container can be granted for the container itself and it's contents by adding accessTo as well as default. You can also set access to only apply to the container itself, as well you can apply access to the contents by themselves.
3. There was another discovery that we had missed the ability to reset the access for a resource back to use it's default, effectively removing the .acl for the particular resource in question.
4. The current sharing pane also has safeguards to prevent deletion of the storage resource permissions so this was added here.

The following is a list of things that were added to support the missing features in the access control dialog:

• Folder-only access.
• Folder-and-contents access.
• Contents-only access.
• Inherited ACLs.
• Resetting a resource back to inherited defaults.
• Protected storage-resource safeguards.
• Explicit error handling for invalid or unsafe ACL operations.

Note: there is one thing still missing is that the current Sharing Pane also has one more role it's Owner (write locked), almost like a "Sharing Manager" so with this permission, which is ['Read', 'Control'] the user can change permissions, but not write to the resource.
