Title: Added the dayClass option

### Docs

The `dayClass` option allows to selectively specify which days on the calendar are enabled or not (at least this is what I need it for, though it can be used for other purposes as well).

- a `Function` - the function is called with one parameter with details about the day being rendered:

{
cname: a list of all classes determined to be applied for this day,
row: the row index that this day is in in the calendar,
col: the column index that this day is in in the calendar,
calendar:
