To be compatible with comments from Disqus (and users unfamiliar with
Markdown), Misaka no longer disables user-inputted HTML, but the
generated HTML is now post-processed and all "unsafe" tags (not
possible with Markdown) are discarded.
Whitelist: p, a, pre, blockquote, h1-h6, em, sub, sup, del, ins, math,
dl, ol, ul, li
This commit also removes an unnecessary newline generated by
Misaka/Sundown.
When an attacker uses a <form> to downvote a comment, the browser
*should* add a `Content-Type: ...` header with three possible values:
* application/x-www-form-urlencoded
* multipart/form-data
* text/plain
If the header is not sent or requests `application/json`, the
request is not forged (XHR is restricted by CORS separately).

Revert "check if Origin matches Host to mitigate CSRF, part of #40"
This reverts commit 9376511485c70deaf908aa67bcdc8f0c9a0b003e.
This reverts commit 9a03cca793.
This reverts commit 4c16ba76cc.
This reverts commit 32e4b70510.
Therefore, only raise Forbidden if Origin (or Referer for MSIE) is sent
(which is a protected header and all modern browsers (except IE)).
Also add a basic unit test which asserts the failure for false origins.
Keep Isso modular, not monolithic. Make it easy to integrate a
web interface or add XMPP notifications.
This refactorization includes minor bugfixes and changes:
* CORS middleware did not work properly due to wrong unit tests
* more type checks on JSON input
* new detection for origin and public url, closes#28
* new activation and delete url (no redirect for old urls, but you can
convert the old urls: copy hash after `/activate/` (or delete) and
open `/id/<id of comment>/activate/<hash>`
* move crypto.py to utils/
With this commit, SMTP is no longer automatically configured: add
`notify = smtp` to the `[general]` section to use SMTP.
