@smn @miltontony I'd like to discuss this PR before I carry on. What are your thoughts on implementing the home page for IoGT? I've put the recent, random content logic in the view code, and thus had to override the springboard view. It's using this springboard branch: universalcore/springboard#27.

Slight concern here about the size of the content list, we should at least flag this with a TODO or a warning.

Coverage remained the same at 19.95% when pulling 9b2b74c on feature/issue-1-override-springboard-homepage-view into 5d8ff04 on develop.

@smn @miltontony ready for review (or re-review). @smn I've changed the IoGTViews.recent_changes method a lot.

>>> filter(None, [None, 1, 2, 3])
[1, 2, 3]

has the same effect.

👍 on the general approach and thanks for going through the effort of not adding caching. Given the client is likely going to still reconsider some of this then I suppose having this stay like this is ok.
