Remove PDF export
As we already decleared in earlier versions, this patch removes PDF
export entirely. It's a not acceptable security risk for every CodiMD
instance.

The current implementation allowed to extract arbitary files from the
CodiMD host and therefore leaking secrets from a `/etc/passwd` to
CodiMD's own config files and all secrets contained in it.

Thanks to Joona for finding this vulnerability in August last year,
which lead to an emergency disabling of PDF exports in 1.5.0.

# API documentation
Several tasks of CodiMD can be automated through HTTP requests.
The available endpoints for this api are described in this document.
For code-autogeneration there is an OpenAPIv3-compatible description available [here](openapi.yml).
## Notes
These endpoints create notes, return information about them or export them.
You have to replace _\<NOTE\>_ with either the alias or id of a note you want to work on.
| Endpoint | HTTP-Method | Description |
|---|---|---|
| `/new` | `GET` | **Creates a new note.**<br>A random id will be assigned and the content will equal to the template (blank by default). After note creation a redirect is issued to the created note. |
| `/new` | `POST` | **Imports some markdown data into a new note.**<br>A random id will be assigned and the content will equal to the body of the received HTTP-request. The `Content-Type: text/markdown` header should be set on this request. |
| `/new/<ALIAS>` | `POST` | **Imports some markdown data into a new note with a given alias.**<br>This endpoint equals to the above one except that the alias from the url will be assigned to the note if [FreeURL-mode](../configuration-env-vars.md#users-and-privileges) is enabled. |
| `/<NOTE>/download` or `/s/<SHORT-ID>/download` | `GET` | **Returns the raw markdown content of a note.** |
| `/<NOTE>/publish` | `GET` | **Redirects to the published version of the note.** |
| `/<NOTE>/slide` | `GET` | **Redirects to the slide-presentation of the note.**<br>This is only useful on notes which are designed to be slides. |
| `/<NOTE>/info` | `GET` | **Returns metadata about the note.**<br>This includes the title and description of the note as well as the creation date and viewcount. The data is returned as a JSON object. |
| `/<NOTE>/revision` | `GET` | **Returns a list of the available note revisions.**<br>The list is returned as a JSON object with an array of revision-id and length associations. The revision-id equals to the timestamp when the revision was saved. |
| `/<NOTE>/revision/<REVISION-ID>` | `GET` | **Returns the revision of the note with some metadata.**<br>The revision is returned as a JSON object with the content of the note and the authorship. |
| `/<NOTE>/gist` | `GET` | **Creates a new GitHub Gist with the note's content.**<br>If [GitHub integration](../configuration-env-vars.md#github-login) is configured, the user will be redirected to GitHub and a new Gist with the content of the note will be created. |
## User / History
These endpoints return information about the current logged-in user and it's note history. If no user is logged-in, the most of this requests will fail with either a HTTP 403 or a JSON object containing `{"status":"forbidden"}`.
| Endpoint | HTTP-Method | Description |
|---|---|---|
| `/me` | `GET` | **Returns the profile data of the current logged-in user.**<br>The data is returned as a JSON object containing the user-id, the user's name and a url to the profile picture. |
| `/me/export` | `GET` | **Exports a zip-archive with all notes of the current user.** |
| `/history` | `GET` | **Returns a list of the last viewed notes.**<br>The list is returned as a JSON object with an array containing for each entry it's id, title, tags, last visit time and pinned status. |
| `/history` | `POST` | **Replace user's history with a new one.**<br>The body must be form-encoded and contain a field `history` with a JSON-encoded array like its returned from the server when exporting the history. |
| `/history` | `DELETE` | **Deletes the user's history.** |
| `/history/<NOTE>` | `POST` | **Toggles the pinned status in the history for a note.**<br>The body must be form-encoded and contain a field `pinned` that is either `true` or `false`.
| `/history/<NOTE>` | `DELETE` | **Deletes a note from the user's history.** |
## CodiMD-server
These endpoints return information about the running CodiMD instance.
| Endpoint | HTTP-Method | Description |
|---|---|---|
| `/status` | `GET` | **Returns the current status of the CodiMD instance.**<br>The data is returned as a JSON object containing the number of notes stored on the server, (distinct) online users and more. |
