Re: [orca-list] Small update; Pluginsystem for Orca using libpeas

Howdy,

i can see this. But i also can confirm that the correct text shows up on 
the screen. this must be an bug in Gtk.AboutDialog or orca itself. So it 
need to get addressed somewhere else.

however, we can strike another task to-do from the list :).
- we now have an base plugin class for more easy extension. It provides 
the basic methods and members what would be needed to be implemented for 
every plugin. so we can provide an unified plugin API now.
let me improve that a bit and move on to have some settings management 
for plugins and its states.

some more goodie:
- uninstalled plugins now disappear immediately instead on next restart. 
i implemented some bits to ignore them. libpeas by its own is not able 
to remove non existing plugins  from its pluginlist at runtime (just at 
next restart). but this should be handled now by the plugin system 
manager class

cheers chrys
