Create JndiObjectFactory to allow JNDI object acquisition during configuration
------------------------------------------------------------------------------

                 Key: SHIRO-217
                 URL: https://issues.apache.org/jira/browse/SHIRO-217
             Project: Shiro
          Issue Type: New Feature
          Components: Configuration
            Reporter: Les Hazlewood
             Fix For: 1.2.0


During configuration, it would be nice to acquire objects from JNDI and use the returned objects
as properties on other configured objects (e.g. in INI config).

There is a JndiRealmFactory that already supports looking up entire Realms from JNDI, but
it is more likely that lower-level objects would be acquired from JNDI instead (e.g. DataSources)
and the Realms would be configured in INI and use those objects.

This would be pretty easy to support:  there is already a Shiro Factory interface and an AbstractFactory
class.  A new JndiObjectFactory subclass could be created that uses a JndiLocator to look
up and acquire objects.

The ReflectionBuilder implementation would need to be changed to handle encountering Factory
objects - if an object in configuration specifies a Factory as a property, the builder needs
to call the factory's getInstance method instead of using the Factory directly.  I think this
could be done in the ReflectionBuilder#resolveReference method without touching any other
code.
