Fixes and improvements on current/selected day highlight

[GoogleCodeExporter]

Hi, 

I noticed that when the current day (today) is on the first week of the painted 
month, it does not get the 'today' class. 

Problem is, when filling the first week inside _buildCalendar, no class is 
specified ever:

        /* The first week */
        for (var j = startIndex; j < 7; j++) {
            a_d[0][j] = {
                d: daysIndex
    , m: currentMonth
    , y: currentYear
    , b: badDates[daysIndex]
            };
            daysIndex++;
        }

I have fixed this, and added another small improvement to highlight both the 
"today" (current day), and the "selected" date (that is, the currently selected 
value. 

The fix and improvement is simple, I am attaching a patch. 

Also, you will need to change the .css as desired to reflect the new 
highlights. I have changed the:

div.datepicker table tbody tr td.today {
   ...
}

style to:

div.datepicker table tbody tr td.today {
 font-weight: bold;
}

div.datepicker table tbody tr td.selected {
 background: #c4d5e3;
}
