This reverts commit 5e7da6678d.

There are better standards in progress like a `capabilities` object:
https://litepub.social/litepub/lice.html

Previously, moving an anonymous post to a blog would instantly federate
the post, regardless of its `created` date. This now respects that value
and doesn't federate the post if its `created` date is in the future.

This is the first part of supporting scheduled, federated posts (ref T567)
but technically fixes #76.

This is a field previously supported by PeerTube, and just recently
added on PixelFed, that should inform other ActivityPub services whether
or not comments are enabled on any given post. WriteFreely doesn't
support comments today, so this will always be false.

This removes HTML, in addition to the Markdown stripping that was
already happening.

This fixes #83

Previously, our hashtag parser would indiscriminately replace
hashtag-like text with hashtag HTML -- including in places it shouldn't
have, like inside code blocks. Along with the v1.7.0 changes to
writeas/saturday, this fixes that and closes #6.

As a bonus, strings of #spaceless#hashtags#in#a#row are now rendered
correctly.

Fixes #50

This closes #40

This allows admin to edit these pages from the web, using Markdown. It
also dynamically loads information on those pages now, and makes loading
`pages` templates a little easier to find in the code / more explicit.

It requires this new schema change:

CREATE TABLE IF NOT EXISTS `appcontent` (
  `id` varchar(36) NOT NULL,
  `content` mediumtext CHARACTER SET utf8 COLLATE utf8_bin NOT NULL,
  `updated` datetime NOT NULL DEFAULT CURRENT_TIMESTAMP,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=latin1;

This closes T533

This helps with post importing and clients that want to support post
scheduling. It also changes how Collection.ForPublic() works, no longer
resetting the ID.

Closes T532

This now sends out a `Create` activity when a post is moved from a draft
to a blog.

This closes #9. Closes T526.

Previously this was only supported on
/api/collections/{alias}/posts/{id} -- this also allows it on
/api/posts/{id}, so things like `Announce`s work.

This closes #4

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

This includes config changes, collections, posts, some post rendering
funcs, and actual database connection when the server starts up.
