As I'm the only code contributor, I'm announcing that URTrator code
is now licensed under MIT license.
Also I'm deprecating Qt5 interface as it is really hard to write Qt
code and create installers with it. Maybe one day I even figure out
how to work with QtQuick (which attracts me more and more ATM) and
URTrator will use it, but not now.
Added language selection combobox in options dialog. Selecting
language here will overwrite language code gathered from system.
Added AcceptedLanguages map to Translator, which holds readable
names and lang-country codes with avaailable languages. Filled
it with languages in which URTrator already translated. Francais
coming :)
