Slightly more efficient and convenient than:
g_simple_async_result_set_from_error (simple, error);
g_error_free (error);
One less GError to copy and destroy.
I pushed a few EShell features up to GtkApplication for GTK+ 3.2,
so we can now trim off the redundancies in EShell.
1) GtkApplication has a new "window-added" signal which replaces
EShell's own "window-created" signal.
2) GtkApplication has a new "window-removed" signal which replaces
EShell's own "window-destroyed" signal.
3) gtk_application_get_windows() now returns a list of windows sorted
by most recently focused, replacing e_shell_get_watched_windows().
4) GtkApplication now provides enough hooks to subclasses that we can
remove e_shell_watch_window() and call gtk_application_add_window()
directly.
We have a confusing array of nearly-identical CFLAGS/LIBS definitions in
configure.ac. Time to simplify. Instead let's just have one definition
that includes all the libraries provided by Evolution-Data-Server (incl.
Camel). That, in combination with GNOME_PLATFORM, gives us most of what
we need for compliation and linking, and we can sprinkle definitions for
additional library dependencies in Makefile.am's as needed.
The EModule, EExtensible and EExtension classes as well as the
e_type_traverse() function have been moved to Evolution-Data-Server's
libebackend library to replace e-data-server-module.c.
Now Evolution-Data-Server modules use the same framework as Evolution.
Convenience function for use in GAsyncReadyCallback functions.
This acknowledges the cancellation, so that the activity's description
changes from "(cancelling)" to "(cancelled)" and the description appears
crossed out in the UI for a moment before disappearing.
Dragging image data or an image URI to the message body while in HTML
mode should insert the image inline, not attach it. Without this the
Picture Gallery feature is pointless.
If a newly-composed message was successfully sent but an error occurred
during post-processing (outgoing filters or appending to a Sent folder),
close the composer window and show an alert in the main window.
