tests: fix assertion rewriting in some tests with pytest-3.0.0+

Since pytest 3.0.0, asserts present in modules that are not directly seen by
pytest as 'test modules', are no longer rewritten to have improved
reporting, unless they are explicitly marked as up-for-rewriting.
Rationale from pytest upstream:

However since we do not want to test different bytecode then you will
run in production this hook only re-writes test modules themselves as
well as any modules which are part of plugins. Any other imported module
will not be re-written and normal assertion behaviour will happen.

This is e.g. the case for asserts in files like
kallithea/tests/api/api_base.py and kallithea/tests/models/common.py.

See
http://doc.pytest.org/en/latest/changelog.html#id13
http://doc.pytest.org/en/latest/writing_plugins.html#assertion-rewriting

This commit registers all modules below kallithea.tests for assert
rewriting, but note that asserts in kallithea/tests/__init__.py itself are
not rewritten as kallithea.tests is already imported when the register
statement is encountered.
Moving the register statement to kallithea/__init__.py would fix that, but
even then asserts in kallithea/tests/__init__.py seem not to be rewritten
(let alone the issue that we do not want a pytest dependency enforced in
kallithea/__init__.py which is also used in production).
Moving the code from kallithea/tests/__init__.py to a proper module, as
suggested by Mads Kiilerich, solves that problem.

.. _customization:

=============
Customization
=============

There are several ways to customize Kallithea to your needs depending on what
you want to achieve.


HTML/JavaScript/CSS customization
---------------------------------

To customize the look-and-feel of the web interface (for example to add a
company banner or some JavaScript widget or to tweak the CSS style definitions)
you can enter HTML code (possibly with JavaScript and/or CSS) directly via the
*Admin > Settings > Global > HTML/JavaScript customization
block*.


Behavioral customization: rcextensions
--------------------------------------

Some behavioral customization can be done in Python using ``rcextensions``, a
custom Python package that can extend Kallithea functionality.

With ``rcextensions`` it's possible to add additional mappings for Whoosh
indexing and statistics, to add additional code into the push/pull/create/delete
repository hooks (for example to send signals to build bots such as Jenkins) and
even to monkey-patch certain parts of the Kallithea source code (for example
overwrite an entire function, change a global variable, ...).

To generate a skeleton extensions package, run::

    paster make-rcext my.ini

This will create an ``rcextensions`` package next to the specified ``ini`` file.
See the ``__init__.py`` file inside the generated ``rcextensions`` package
for more details.


Behavioral customization: code changes
--------------------------------------

As Kallithea is open-source software, you can make any changes you like directly
in the source code.

We encourage you to send generic improvements back to the
community so that Kallithea can become better. See :ref:`contributing` for more
details.
