Fix xfdesktop --reload in spanning mode (Bug 10853)

When issuing an xfdesktop --reload while in spanning wallpaper
mode, all the monitors would update their backdrop which means
the wallpaper of the last monitor would then be shown. This
fixes the logic to continue to show the wallpaper for the first
monitor as intended.

settings: Fix background color loading

The issue was launching xfdesktop-settings changed the
wallpaper background color, either to black or #7f000 or
some other color.
There's a bit of a mixup in the code, there's color 2s where
there should be color 1s. With these corrected the colors
should properly be loaded and old versions should be migrated.
Bug reported to launchpad but never sent up to xfce's bugzilla:
