[Qgis-developer] Improvements in Actions

[Paolo Cavallini]

Hi all.
Thanks to ongoing support from Regione Toscana, and to the brain&fingers of Giuseppe 
Sucameli, now actions are IOHO substantially improved:
* now we have a button to launch actions directly from the canvas
* new expressions builder engine can be used to evaluate feature actions
* possibility of adding custom patterns for replacement (e.g. $clickx and $clicky to 
use the coordinates of the clicked point)
* cleanup of the interface:
. move the "capture output" checkbox away from the "insert field" combo
. display add and update buttons below the edit action widget (following the "new 
shapefile" UI style).

Feedback welcome.
All the best.
