Simple permission mapper can't represent wildcards or spaces

The inability of the simple-permission-mapper to handle wildcards forces the user to utilize complex logical permission mapper chains to achieve common use cases. This makes simple changes, such as adding an additional permission to a user unnecessarily complex. In addition to construction complexity, modifications performed by non-experts are likely to lead to unintended behavior, including accidentally granting permissions to a user that should not have them.

This is readily apparent by even our default configuration requiring the use of 3 permission mappers to handle the basic case of denying anonymous users and allowing everyone else.
