Igor Kushnir 5034348c1a Allow silencing failed-loading-resource warnings 
When a referenced audio resource is not found in a DSL or XDXF
dictionary, GoldenDict searches for this resource by filename in all
other dictionaries within the current group. Naturally, the file is
absent from most dictionaries (see #970). Therefore a "Failed loading
resource" warning is printed for almost every dictionary in the current
group.

These warnings are by far the most frequent on my system. And in the
scenario described above there is nothing wrong at all. So the user may
want to silence these warnings to help notice less frequent and more
important messages. Implement categorized logging to enable this
customization. These warnings can now be disabled by adding the
following line in the [Rules] section of a logging configuration file
(e.g. ~/.config/QtProject/qtlogging.ini on GNU/Linux):
    goldendict.dictionary.resource.warning=false
