sounds complex, but really it just reorganizes the posting options and
adds a seperator line

they have been loaded and favourited/reblogged from another source

Since the status JSON returned from public/hashtag streams does not
contain favourited/reblogged attributes, merging them should not
override existing ones.

FanOutOnWriteService. The only recipient-specific part on them
is reblogged/favourited. But since only newly created statuses
appear on them, it is safe to assume that both attributes would
be false

redis-backed "mentions" timeline as redundant (given notifications)

Changing the way the background image is positioned and the box is sized should fix problems with the text overlapping the image on mobile browsers and Edge.

nested inside a common parent (<Account>), instead they all embed <HeaderContainer />

Currently we have the problem where the follow request button is missing
from the Follow request tab. This means that when you visit that tab you
either have to press the back button in the browser or re-enter the home
page, which breaks the app flow.

This will resolve that issue by adding a new back button to that tab,
in the same way that the public timeline, and favourites have.

remove button outlines on-click for retweet, boost, favourite, and reply
buttons

fix ProcessFeedService pushing status into distribution if called a second time
while the first is still running (i.e. when a PuSH comes after a Salmon slap),
fix not running escape on spoiler text before emojify

Currently we have two problems that are resolved by this change.

The first is that we have a dependency on Google Fonts, which means
that should it ever go down, or it have issues we would also have
issues. This will resolve this by moving the dependencies we load from
there to the local server.

The second issue is that Google Fonts is currently returning the
`local()` css font source. This causes a problem where the users browser
fails to fallback to a missing glyph, resulting in many unusual
characters displaying the failure glyph. This will resolve this by
creating a font-family definition that does not use the `local()`
source.

I did not update the error pages with local fonts, they still use the
remote google fonts api, so they're a self contained page that does not
use the asset pipeline.

This resolves tootsuite/mastodon#531 and tootsuite/mastodon#12

improved how "show more" link looks

Currently, the getting started text fails WCAG standards for color contrast by a lot. Especially on the part overlapping with the elephant graphic which is nearly unreadable even for users with 20|20 vision. This change doesn't fix the elephant overlap but at least makes the text meet AAA WCAG Small Text color contrast standards, making it easier to read.
