Implements latest post summary in Insights

[astralbodies]

Closes #289
New UI:

Test scenarios:

1. No data.
2. Slow/crappy data (using link conditioner).
3. iPad and iPhone - ensure rotations work right.
4. Sites with no posts.
5. iOS 9, 8 and 7 (I'll take care of most of this).

How to test:

• Local deployment if you're into Xcode 7.
• StatsDemo which I'll be sending out soon.

Needs Review: @jancavan, @jleandroperez, @daniloercoli

Updated the Travis build with this fix to let xctool actually run the unit tests properly - facebookarchive/xctool#528 (comment)

StatsDemo build 39 has this PR included.

This is me not mentioning how fragile the  looks like!

I know, I KNOW 😄

Not sure exactly why, but i'm seeing this in the Console logs (Xcode 7):

Sep 21 16:51:25  StatsDemo[25671] <Error>: CGContextSaveGState: invalid context 0x0. If you want to see the backtrace, please set CG_CONTEXT_SHOW_BACKTRACE environmental variable.

@astralbodies I've got a post with 0 likes and 0 comments (plus a bunch views). Tapping over any of the rows always leads to the same details view, would that be expected?

[jleandroperez]

And yet another comment (sorry about the spam!). The Post Summary's Details view shows the Post Title within the View Controller's title field.

It's way too easy to get that string clipped. Comment / suggestion, would it be possible to perhaps reuse the Latest post summary cell (or a slice of it), so that we get at least two lines to render the title (+ a smaller font) ?.

This is how my last post looks like:

[astralbodies]

Re: tapping the rows in the insights getting to the same post details - that is correct behavior for right now. I did open another issue for the post details title in the navigation bar.

Thanks for reviewing @jleandroperez. I need to make the view controllers smaller and it is on my radar soon. :stabby:

?

[jleandroperez]

Thanks for checking @astralbodies!

[jancavan]

@astralbodies great job adding this module to Insights! 2 minor comments :)

1. post title text should be a link that jumps to the blog post itself
2. Likes and Comments should not be links since we only show data for Views on the post summary pages

[astralbodies]

Thanks @jancavan - I'll make this another issue 👍
