scripts/i18n: introduce new i18n maintenance script

The translation files in the Kallithea repository contained references to
the location(s) of each string in the repository. This is useful to
translators, but is not needed for all other users.

The big problem with that information is that it changes very commonly as a
result of normal development in Kallithea, causing a lot of unimportant
delta in the Kallithea repository, thus causing unnecessary repository
growth.

A script 'i18n' is added to help maintain the i18n files. Functionality will be
added later.

===================
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 occurred 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.
