[AC-4839] Appcelerator Documentation Site : Titanium SDK - broken link identified within article

Problem

The link at the bottom of Layouts, Positioning, and the View Hierarchy results in 404 Page not found notice on the target site

Test case

Navigate to http://docs.appcelerator.com/platform/latest/#!/guide/Layouts,_Positioning,_and_the_View_Hierarchy in a web browser.

Scroll to the bottom of the page to the section titled "References and Further Reading"

The 3rd link with the caption "Titanium app for explaining layout mechanisms" points to http://blog.krawaller.se/titanium-app-for-explaining-layout-mechanisms

For clarity, the correct target for this link is: http://blog.krawaller.se/posts/titanium-app-for-explaining-layout-mechanisms/
