Remove unused "backgrounds-liststore" object from .ui file, and
add remove button.
Make remove button sensitive for files that were copied to the cache,
and implement remove itself.
Remember needs_download when copying CcBackgroundItem objects.
Make "Add" button unsensitive in chooser when background was
already added to the list, to avoid duplicates.
Ellipsise background label.
When we're creating our new item for custom wallpapers, make
sure that we update the ->current_background, otherwise we'll
still be displaying the previous configuration.
Save the current background as XML, and try to load it back up
when starting. If the saved background pretty much matches what we
have in GSettings, then it's the same item, and we try and remember
all the metadata, including the name.

Now we'd just need gnome-bg to make the jump.
This also fixes unique IDs for the wallpapers source, as
multiple backgrounds can be defined in a single XML file.
Instead of reusing the item from the list store, otherwise we
might be tweaking properties for an item that we shouldn't,
and leaking user preferences into the "static" list store.
When setting a new background. That ensures that we don't lose
existing settings when the background item doesn't provide one
(for example, setting the background colour when setting a picture
item).
It now is a full GObject, will be able to track the original
XML file for a wallpaper, as well as which values are set in it.
This will allow us to restore wallpapers properly, and only offer
editing options when those aren't already hard-coded inside the
item.
g_settings_delay() doesn't work like GConf's changesets. Either
you create a separate GSettings for non-delayed application,
or you call g_settings_apply() any time you want changes applied.
The gnome_wp_item_update_size() code was working off old data.
We need to copy the height and width as well if we want it to
match the current background. The next call to _update_size()
will fill in ->size if it wasn't already set.
Add icon to represent slideshows, always show a name for the
currently set background on startup, show whether a background
is a slideshow, and its pixel size if available.
The style wasn't set properly on startup, and then incorrectly
applied to the preview because the numbering of the items in
the style-liststore doesn't match the GDesktopBackgroundStyle
enum 1-to-1.
Take a reference on the panel object when the asynchronous copy is started
so that it is still valid in the callback when the panel is being
destroyed.
