commit f84d012dc997211a43236325bca50dc7092ec3e3
Author: Andrzej <ndrwrdck at gmail.com>
Date:   Sat Mar 31 21:57:43 2012 +0900

    Making the plugin a library and a subclass of XfcePanelPlugin
    
    The plugin is now installed as a library and to a different directory
    (following convention of other plugins).
    
    The plugin is now an object of IndicatorPlugin class, which extends
    XfcePanelPlugin. This is for making definition of properties and integration
    with xfconf easier.
