issue #27
Translate Month
Added Method to get translated month name. It was necessary to reduce one month first in order to get the proper translated value. It seems locales is one month ahead. It was not possible to add an "empty month" (like in the translated month shortcuts) - this would destroy "month dropdowns". Changed Report sidebar to display translated month names in statistic.
