KHoliday::HolidayRegionSelector: emit signal when modified
Review Request #100619 - Created Feb. 10, 2011 and submitted - Latest diff uploaded
Makes HolidayRegionSelector emit a signal when something is modified in the widget. Needed for enabling Apply button on plasmaclock config [http://git.reviewboard.kde.org/r/100620/].
Works fine so far, although I'm not sure if the naming is OK.
