There are actually a few 'background' tags floating around in the... background.

...Ok, that one was terrible. In all seriousness though:

[tag:background] Is used generically for both background tasks, and background images. These will need to be manually split out into the appropriate tags.

As for the appropriate tags, there seems to be a few of each. These could probably be merged together

- [tag:background-job] -> [tag:background-process] 
- [tag:background-image] -> [tag:desktop-background]

Thoughts?
