Formats all component hbs markup to a max char length of 80.

[klepas]

Description

Formatting changes to our example markup for each component such that there’s a max of 80 chars per line. This is largely to make reading source files a bit easier, and to improve the readability of the pre formatted markup examples within the guide (less side scrolling, hopefully).

Only holds formatting edits; no markup itself was altered..

@danwhitmarsh Hey, could you review this briefly please? (:

I will have to either rebase this, or the branch of PR #421 since these filenames have had their extensions changed (from .hbs -> .html).
