In the current setup users could be tricked into deleting their data by
providing a malicious link like `[click me](/me/delete)`. This commit
prevents such an easy attack and need the user's deleteToken to get his
data deleted. In case someone requests his deletion by email you can
also ask him for this token.
We can add a GUI that shows it later on.

into a non-inline version is the way to go.
This implementation probably needs some beautification. But already fixes
the bug.
