utils: make API key generator more random
The API key generator abused temporary filenames in what seems to be an attempt
of creating keys that unambiguously specified the user and thus were unique
across users. A final hashing did however remove that property.
More importantly, tempfile is not documented to use secure random numbers ...
and it only uses 6 characters, giving approximately 36 bits of entropy.
Instead, use the cryptographically secure os.urandom directly to generate keys
with the same length but with the full 160 bits of entropy.
Reported and fixed by Andrew Bartlett.

Debugging Kallithea
===================
If you encounter problems with Kallithea, here are some instructions
on how to debug them.
.. note:: First make sure you're using the latest version available.
Enable detailed debug
---------------------
Kallithea uses the standard Python ``logging`` module to log its output.
By default only loggers with ``INFO`` level are displayed. To enable full output
change ``level = DEBUG`` for all logging handlers in the currently used .ini file.
This change will allow you to see much more detailed output in the log file or
console. This generally helps a lot to track issues.
Enable interactive debug mode
-----------------------------
To enable interactive debug mode simply comment out ``set debug = false`` in
the .ini file. This will trigger an interactive debugger each time
there is an error in the browser, or send a http link if an error occured in the backend. This
is a great tool for fast debugging as you get a handy Python console right
in the web view.
.. warning:: NEVER ENABLE THIS ON PRODUCTION! The interactive console
can be a serious security threat to your system.
