Notes

Test Steps

1. On a logged in account with edits on the primary language
2. Navigate to activity tab
3. Scroll through to timeline to ensure edits are properly placed throughout (chronologically)
4. Ensure you are able to tap into the edit to see the diff
5. Ensure you do NOT see edits unless you're logged in
6. Ensure you are unable to longpress/swipe on edit items, but can on the rest
7. Look at cleanup and ensure it looks proper

Requirements:

-[x] Add edits into the timeline at the bottom of the Activity tab
-[x] Each edit includes a “View changes” leads to diff of your edit
-[x] Tapping on the article title should also lead you to the diff of your edit
-[x] Edits should be in chronological order, intermixed with articles read and saved
-[x] Edits should only be included in the timeline for logged-in users (temp accounts are treated like logged-out users)
-[x] It's acceptable to only have the past 500 edits represented in the timeline
-[x] No swipe option on edit items
-[x] No longpress option on edit items
-[x] Cleanup: Create a UserContributionsDataController, have it make the same call that YearInReviewEditCountSlideDataController does. Ask YearInReviewEditCountSlideDataController and YearInReviewDonateCountSlideDataController to fetch the data from UserContributionsDataController instead of making the call itself. Allow call to be made without a start/end date and with a maxlimit of 500.

Looks good! Most comments are about fixing changes resulting from my poor engineering notes in the task description.

One thing that feels like a bug to me is that the diff screen after pushing still shows the bottom tab bar.

The pattern in the rest of the app is to hide that tab bar upon any push from a root view. We generally play wack-a-mole for that. We have never pushed on this view directly from a root view before, in the past other views pushed on have already hidden the tab bar by the time the diff view is pushed.

To fix this one context, just add this to the end of the DiffContainerViewController init.

hidesBottomBarWhenPushed = true
