  Added:       src/java/org/apache/log4j/plugins Plugin.java
  Log:
  Moved a copy of Plugin into the sandbox repository.
  
  This is to add the setActive(boolean) JavaBean style setter to compliment
  the isActive() getter method.
  
  The idea here is that something like Chainsaw should be able to manage
  the active nature of a Plugin, and this method needs to be exposed.

  /**
    Defines the required interface for all Plugin objects.
  
    <p>A plugin implements some specific functionality to extend
    the log4j framework.  Each plugin is associated with a specific
    LoggerRepository, which it then uses/acts upon.  The functionality
    of the plugin is up to the developer.
  
    <p>Examples of plugins are Receiver and Watchdog. Receiver plugins
    allow for remote logging events to be received and processed by
    a repository as if the event was sent locally. Watchdog plugins
    allow for a repository to be reconfigured when some "watched"
    configuration data changes.
