files: restore 'Show Authors' functionality

Commit d66201a7ce6e ("files: change "callbacks" function to the more
descriptive name "post_load_state" and let it take an actual state data
object") broke the 'Show Authors' button when visiting a file
in the files browser. The button normally shows a count of authors and their
avatars, but after the aforementioned commit it did nothing.

Following patch would have fixed the problems in commit d66201a7ce6e:

$(document).ready(function(){
var state = {
+ data: {
node_list_url: node_list_url.replace('__REV__',${h.js(c.changeset.raw_id)}).replace('__FPATH__', ${h.js(h.safe_unicode(c.file.path))}),
url_base: url_base.replace('__REV__',${h.js(c.changeset.raw_id)}),

+ }
}
- post_load_state(State.data); // defined in files.html
+ post_load_state(state.data); // defined in files.html
});
</script>


But, later the code got refactored more, and commit 006d68c4d7b9 ("files:
use the web browsers built-in js history instead of native.history.js")
broke the feature further: the click handler for the button no longer got
installed on the 'document-ready' event, but only when a new 'state' is
loaded. And it seems there is never a situation where a new state preserves
the button, so it makes no sense installing the click handler at that
moment.

Instead, move the click handler back to the 'document-ready' event.

=============
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 the Kallithea root
directory, 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: 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::

    kallithea-cli extensions-create -c 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.
