repo groups: make it possible to remove own explicit permissions, now when group owners always have admin permissions

Until recently, group owners very given explicit admin permissions on repo
group, and special care was taken to make sure they didn't remove themselves.

Now we always give admin permissions to owners, and don't care about the
explicit permissions. We no longer add them when creating groups or changing
owner. There is no migration step to remove redundant permissions, but we
should allow group admins to remove them. This change will thus remove the
mechanism for preventing removal of own/owner permissions.

=============
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*.


Style sheet customization with Less
-----------------------------------

Kallithea uses `Bootstrap 3`_ and Less_ for its style definitions. If you want
to make some customizations, we recommend to do so by creating a ``theme.less``
file. When you create a file named ``theme.less`` in directory
``kallithea/front-end/`` inside the Kallithea installation, you can use this
file to override the default style. For example, you can use this to override
``@kallithea-theme-main-color``, ``@kallithea-logo-url`` or other `Bootstrap
variables`_.

After creating the ``theme.less`` file, you need to regenerate the CSS files, by
running::

    kallithea-cli front-end-build --no-install-deps

.. _bootstrap 3: https://getbootstrap.com/docs/3.3/
.. _bootstrap variables: https://getbootstrap.com/docs/3.3/customize/#less-variables
.. _less: http://lesscss.org/


Behavioral customization: Kallithea extensions
----------------------------------------------

Some behavioral customization can be done in Python using Kallithea
``extensions``, a custom Python file you can create to extend Kallithea
functionality.

With ``extensions`` 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::

    kallithea-cli extensions-create -c my.ini

This will create an ``extensions.py`` file next to the specified ``ini`` file.
You can find more details inside this file.

For compatibility with previous releases of Kallithea, a directory named
``rcextensions`` with a file ``__init__.py`` inside of it can also be used. If
both an ``extensions.py`` file and an ``rcextensions`` directory are found, only
``extensions.py`` will be loaded. Note that the name ``rcextensions`` is
deprecated and support for it will be removed in a future release.


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.
