Windows 8 Build 7776.0.fbl grfx dev1.100708-1700：修订间差异

In preparation for the soon redesign of the Help and Support app, the main page of the app has received a few design updates. Instead of the "Find an answer quickly" paragraph being the title, a seperate "Windows Help and Support" title is now used instead, with the paragraph, magnifying glass and the "Enter a few words [...]" sentence being moved to a seperate gray rectangle that extends to the borders of the app. The "Not sure where to start?" heading has been made smaller, and the dots used for the lists have been changed from squares to circles, alongside the spacing between them being made slightly bigger. Lastly, the seperation between the "More on the Windows website" section has been removed, and a sub-heading is now used for that section instead, with all of the content present in that section now being written in italic.
