follow Python conventions for boolean values

True and False might be singletons and the "default" values for "boolean"
expressions, but "all" values in Python has a boolean value and should be
evaluated as such. Checking with 'is True' and 'is False' is thus confusing,
error prone and unnessarily complex.

If we anywhere rely and nullable boolean fields from the database layer and
don't want the null value to be treated as False then we should check
explicitly for null with 'is None'.

Debugging RhodeCode
===================

If you encountered problems with RhodeCode here are some instructions how to
possibly debug them.

** First make sure you're using the latest version available.**

enable detailed debug
---------------------

RhodeCode uses standard python logging modules to log it's output.
By default only loggers with INFO level are displayed. To enable full output
change `level = DEBUG` for all logging handlers in currently used .ini file.
This change will allow to see much more detailed output in the logfile 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
.ini file, this will trigger and interactive debugger each time there an
error in browser, or send a http link if 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. ** NEVER ENABLE THIS ON PRODUCTION ** the interactive console
can be a serious security threat to you system.
