disabling plugins using config working now
- added test for PluginFactory to test disabling of plugins
- added base class for non-database test cases
- little more work on permissions (added default mode constants and option)
added new options for plugins and permissions to sample config files
implemented access tests in ModelFactory
- ModelFactory is throwing access denied exceptions now
- PermissionFactory checks all permission plugins for access
- Permission plugins by default return the default access mode
- TODO: needs testing and implementation of a local auth system
