Added support for more languages

It is now possible to choose the language for the month and weekday names from a larger selection of languages. Unfortunately, support for chinese/taiwanese has been temporarily dropped.

It takes several minutes to finish the calibration(around 10 mins for the 2-colour displays and around 20 mins for the 3-colour displays) so please choose hours where you are less likely to need the display. It is recommended to calibrate at least thrice a day.</p></div>
