Today isn't highlighted in datepicker

[prjseal]

When using the datepicker, today is not highlighted which makes for a poor user experience.

I was expecting to see today's date highlighted somehow, perhaps like this:

There is a style for the border colour of the element with the today class on it, but there is no border set.

I have created a fix for this issue already.
