New:

* the program's language is now selectable at start-up - English and German are available

* user can select that a maximum number of different colors is used (two arbitrary balls won't have the same color in case of 'Square1 - small', 'Square2 - small' and 'Triangle - small') - selectable on the 'Options - Special' page

* game starts without message dialog when user has clicked on the playboard

Fixed bugs:

* result dialog showed false value for the number of tries needed to find the combination of colors
