Previously one could override notes in FreeURL-mode by sending multiple POST requests to the /new/<alias> endpoint. This commit adds a check for an already existing note with the requested alias and returns a HTTP 409 Conflict error in case that happens.

This checks all files that claim to be an svg (by their extension) that they really are and defines the typeFromMagic accordingly
Files that got identified as jpg, but have the extension .jpeg get their extension fixed.
The files extensions will work in all cases now.

When FreeURL mode is enabled and you called the /download route, the note was created and the user redirected to the blank note.
This is caused because the findNote method automatically creates a note when no existing one is found.
This commit adds a new parameter to the findNote method which allows to disable this behaviour. In that case a HTTP 404 error will be returned.

As explained in #391, the previous note creation logic didn't handle the case "alias is set, but it's not a file on disk". The fix introduces a separate if-statement for this scenario at the cost of a doubled filesystem read access.

This patch reworks the error messages for image uploads to make more
sense.
Instead of using the current `formidable error` for everything, all

This patch fixes the issue of unauthenticated users, being able to
upload files, even when anonymous edits are disabled.
It's implemented by blocking uploads when either `allowAnonymous` is set
to `false` for all unauthenticated users, unless `allowAnonymousEdits`
is set to true, to make sure anonymous editors still experience the full
feature set.

This patch fixes a security issue with all existing CodiMD and HedgeDoc
installation which allows arbitary file uploads to instances that expose
the `/uploadimage` API endpoint. With the patch it implies the same
restrictions on the MIME-types as the frontend does. Means only images
are allowed unless configured differently.
This issue was reported by Thomas Lambertz.
To verify if you are vulnerable or not, create two files `test.html` and
`test.png` and try to upload them to your hedgedoc installation.
```
curl -X POST -F "image=@$(pwd)/test.html" http://localhost:3000/uploadimage
curl -X POST -F "image=@$(pwd)/test.png" http://localhost:3000/uploadimage
```
Note: Not all backends are affected. Imgur and lutim should prevent this
by their own upload API. But S3, minio, filesystem and azure, will be at
risk.
Addition Note: When using filesystem instead of an external uploads
providers, there is a higher risk of code injections as the default CSP
do not block JS from the main domain.

This patch fixes the currently broken redirect on login when people try
to access a site they have no access to, they are redirected to the main

back to the note they edited.

Depending on how the system was setup, this bug lead to keep user's data
around even after a successful deletion of user'S account. This patch
will make sure the missing database constraints are implemented and
missed out deletions are executed.
This bug was introduced to insufficent testing after implementing the
feature initially. It was well tested, using the app process itself, but
the migrations where missed out. I'm currently not sure, if there was
also a change in how sequelize handles cassaded deletion, since I'm
unter the impression that before switching to sequelize 5, this feature
has worked. But I haven't verified this.
No matter what, the cleanup process is rather straight forward and will
be invoked on migration, but can also be done manually using the new
`bin/cleanup` script.
This change will result in a release 1.6.1.

As we noticed in our poll about CDN usage, that most people
intentionally turn it off, but very little intetionally turn it on or
leave it on. [1]
There is also strong indicators that CDNs don't really provide any
benefits in loading time and due to the small deployments of CodiMD,
there is no big savings due to CDNs either. [2]
Therefore this patch changes the CDN default settings to off in order to
reduce the exposed user data.
