* Moved from GLib to GIO in file handlings. It means that now the editing operations (open/save/rename/etc.) are faster. Moreover, after the GIO migration, Scratch gained the support to URI file handling.
* Devhelp plugin was added to the default set of extensions for Scratch. It is an easy tool to consult all documentations about GNOME's libs directly from the text editor
* Plugins view in Preferences dialog had some changes. Now the plugins have icons and the About dialogs relative to them are from Granite, not from Gtk as default.
* Terminal plugin got some improvements. Added Copy/Paste feature.
* Share button is now hidden when there is nothing which wants to share files.
* General bug fix
