Oh the irony: Let's update H5BP to v4.3.0 first, even though this doesn't belong in this feature branch.
Newline at EOF.
Fix version number.
Slightly increase border-radius for the sidebar search.
Use the "Light" color for the search input.
A messy one:

* Switch to Tumblr's own like- and reblog-buttons.
* Reference minified version of masonite.js.
* Remove line-through for hovered links in the sidebar; instead, use the "Accent"-color for consistency.
* Fix transition-duration of the "Dog Ear Zoom Icon".
Update changelog.
Merge branch 'feature/native-tumblr-reblog-and-like-links' into develop
