A Bunch Tell is now Musing Studio.

Ref T770

This file is compiled from other sources, and thus shouldn't be
included in the repo.

Ref T401

Ref T319

Ref T401

From the writeas org on GitHub.

This includes the platform mark with each login button and uses
brand colors. It also uses the same style on the Account Settings
page. And it wraps buttons on login / signup pages.

This adds a "load more" button to the bottom of the draft posts page,
which calls /api/me/posts with new parameters and the current page
number. It then populates the page accordingly.

Ref T696 - load anon. posts with ?anonymous=1&page=1
Ref T401 - completes UI for post loading

Fixes #41

- Break up linked / to-link sections
- Add logos for all services
- Lay out buttons horizontally
- Tweak the copy

Ref T713

This takes styling from the Classic Editor on Write.as.

It adds all application code for auto-saving the title, publishing it
with the post body, and including it in the word count.

This keeps it consistent with all our other CSS.

Posts without an explicit title render the date as the post header in
lists of posts (like on the blog index and tag pages). This updates
localdate.js to properly adjust those dates, too.

- Move them above local login form
- Restyle as side-by-side buttons

Ref T712

this adds a helper script to rewrite all time elements with a proper
datetime attribute into the users locale via the browser
navigator.language.

collection, collection-post and chorus-collection-post templates now
include this script

This reverts commit 25145296b3.

with only the single script, there were still many requests to a CDN.
this fixes that and speed up the page load a bit as well.

this includes a copy of mathjax@3.0.0/es5/tex-mml-chtml.js

Previously it referenced an image on write.as and had the incorrect
og:url property. This also fixes the canonical URL on single-user
instances. Closes #91

(instead of the Write.as "w")

These were missing.

This closes T551

Part of T551

This fixes things like em-dashes and adds new glyphs.

- New editor nav
- New backend nav
- Support for drafts
- Different footers on backend

This includes the '/' route handler
