Hi all,

This new 0.3.0 release has an stable API more robust. I will try do not
change this API for a time. 

We use a new trigger mechanism with GtkSourceCompletionTrigger
interface. This do the new trigger creation easy and the completion or
application can control the registered triggers.

If you want to try it, please feedback the experience...

Regards,
