admin: apply LOWER() on journal filtering term for suffix/infix matching

Before this revision, LOWER() (via func.lower() of sqlalchemy) isn't
applied on journal filtering term for suffix and infix matching, even
though it is applied for prefix or immediate value matching.

This causes unexpected result with DBMS, which compares strings case-
sensitively by default.

This revision applies LOWER() on journal filtering term for
suffix/infix matching, to filter journal case-insensitively.

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.
