* Rhizome: add site-theme.xsl, eliminates the need for a "theme.xsl" alias
* Rhizome: Always use fine-grained authentication, including with RxUpdate.
To support this, enhance authorization:
** Add new fine-grained permission: auth:permission-new-resource-statement
** Moved class based authorization to a separate step after updates are complete.
This eliminates changes with class inferencing during change authorization
thus simplying authorization behavior and makes it harder to create privilege escalation holes.
** reauthorize all the properties for all dependent resources when a
subproperty of auth:requires-authorization-for is added or removed
** Add several property-value predicates and allow custom property-value
predicates to be created (via the new 'auth-value-matches' XPath function).
** The new with-new-resource-value property-value predicate allows for access
tokens to only be applied to new resources created during the transaction.
This can be used for example, to allow a guest account to create a new user
for herself, but not modify or create other objects.
** Add a can-assign-guard property for users and roles and a corresponding
with-value-user-can-assign-guard property value predicate.
** Add a auth:grants-rights-to property to allow specific resources to execute
with extra privileges
** replaced find-unauthorized XPath function with authorize-statements
