* Remove 'Set as background' from conf_wallpaper and add it to e_bg
together with the other code that already was handling
'*.edj'. This makes more sense and will enable the action in
presence of both versions of wallpaper dialog;
* e_utils got pieces required by e_bg that could be used elsewhere,
one is the dialog to query for options to import, the other is what
really generates the conversion (import) of image->edj.
* conf_wallpaper: import thing is way too messy, needs cleaning or
removal. I don't care much about it as I plan to improve wallpaper2
instead.
