Softricks Javascript Calendar
Author : Kedar R. Bhave

Modification History :-
=======================
v1.0    1st Jan 2000.
v1.2    Added Navigation buttons, and Print capability.
v1.21   Bugfixes, Highlighted Weekend days
v1.22   Includes first days for the next month (grayed-out) in the month
                view (after the last day of the month).
        Added support for MONTH DD, YYYY format.
        Fixed a bug. Year/Month values were assumed to be passed as strings.
        (dt: 09/13/2000)
v1.3    Bugfixes
                Can work as a popup or INLINE calendar with an extra parameter.
                Better looks. Border, Title, Background all added and customizable.
                (dt: 09/25/2000)
v1.4    Added code to close the Inline calendar (just as popup),
                        when the user selects a date.
                User can keep the calendar open or close it every time he selects
                        a date.
                Calendar can now replace the value in the text item or append to it.
                        Useful if you want to select multiple dates. Keep it open and
                        select dates one by one.
                Calendar can now return Day-Of-Week instead of date
                        (default is date).
                Pass other customization parameters to the Calendar using a 5th
                        argument to show_calendar function. The argument is of the form
                        "name1=value;name2=value2;...". Valid names include -
                        CloseOnSelect=Yes/No;
                        AppendOrReplace=Append/Replace;
                        AppendChar=;;
                        ReturnData=Date/DOW;    (Date or Day-Of-Week)
                (dt: 11/09/2000)
v1.4_IIR (01/24/2005) by David Johle @ IIR
   Removed isIE/isNav code variations because modern Mozilla based browsers don't misbehave
      or use non-standard tags (e.g. <LAYER>) like the old Netscape 4.x browsers.
   Added function for turning month words into month numbers
