		Calendar gadget
		
		degac + sebholl gadget redraw improvements
		
		07 jun 2009		first release, some basic fixes
		08 jun 2009		the Calendar Gadget returns (every time you click/change the date) the new date
					in the EventExtra field
					you can have multiple appointments in the same date (dd-mm)
					you can have 'fixed' appointment for a specific year (dd-mm-yyyy)
					
		13 jun 2009		SetGadgetColor support
					Some bug fix with calendar length & panel
					CreateCalendar has 2 styles
					- CAL_WEEKEND (1) : the SUNDAY and SATURDAY label are both 'coloured'
					- CAL_HIDDEN  (2) : the selected day is not showed on the calendar	
					Changed GetCalendarAppointment & RemoveAppointments to get / remove a single appointment
					Appointments are 'numbered' and displayed automatically


		02 ago 2010
		
					Added:
					
						+ SetCalendarLocale(calendar:tcalendar,weeks,months)
						
						To localize days name and months
						usage:
						
						SetCalendarLocale(cal,"Lu,Ma,Me,Gi,Ve,Sa,Do","Gen,Feb,Mar,Apr,Mag,Giu,Lug,Ago,Set,Ott,Nov,Dic")
						
						Day week and months *MUST* be separated by commas
						

						+ SetCalendarHoliday(calendar:tcalendar,date,descriptions)
						
						To add an holidays calendar
						
						Usage:
						
						SetCalendarHoliday("01-01,25-12","New Year,Christmas")
						
						dates and descriptions *MUST* be separated by commas
