GtkSourceCompletion: New Features and screencast

Hi all,

	I have added two new features to GtkSourceCompletion:

1.- Popup position: When you trigger an event you can pass the popup
position type. Currently supports:

	GSC_POPUP_POSITION_CURSOR,
	GSC_POPUP_POSITION_CENTER_SCREEN,
	GSC_POPUP_POSITION_CENTER_PARENT

2.- Popup filter: I have added a filter in the popup and you can
enable/disable it when trigger an event. This filter only the current
proposals into the popup.

You can take a look at this screencast:
