Adding scope field to generic OAuth

Drop the /tags/{tag} route

Automatically resize CSS editor

Fix escaping in post summary

Some OAuth providers (like Mastodon) do not use the default
"read_user" scope, instead offering a custom scope. The config.ini
for generic OAuth now contains a "scope" field, allowing the admin
to set the scope manually (it defaults to "read_user" if blank).

Support Web Monetization

Fix header spacing on pinned posts

Fix removal of query parameters on youtube embed links

Some WriteFreely instances are completely private, and thus have no need for public-
oriented features like Web Monetization. Like federation, this gives admins control
over whether or not the feature is enabled for users.

update getCollectionPage

Update getCollectionPage godoc and reduce logic and variable assignments

Closes T708

The header shouldn't include the `dated` property, since we don't display a date
on pinned posts. This fixes that.

Unescaping post content after sanitizing it. This will prevent double
escaping when summary is rendered by html/template package which does
escaping by default.
Fixes #340
