[content hub plugin] add "wallpaper" to the content hub

[Olga Kemmet]

Steps to reproduce:

1. Open gallery app
2. Navigate to your photos
3. Tap on any picture to view
4. Tap again to invoke the header
5. Tap the action menu on the left in the header
6. Select the SHARE PHOTO action

Actual result:
The content hub is invoked with Facebook and Messaging apps

Expected result:
The available destinations in the content hub should include WALLPAPER. This way user has an easy way to add content and change backgrounds.

Why Wallpaper when the setting is Background, I would expect these to be consistent
We have the reverse functionality to pull the images via settings.
Usability reported this as Medium, "Change background for the phone was easy" and 1 participant failed the task.

Agree with Pad, should be Background everywhere.

Will mark this a low priority as there is already a way to achieve this through system settings - and I guess adding Background in content hub would require a fair amount of work

I don't mind weather this is called BACKGROUND or WALLPAPER. Whatever works better. :)
