Today doesn't highlight when it is a weekend

[reustle]

The background-color property of .fn-gantt .sa, .fn-gantt .sn (line 144 of style.css) is overriding the background-color property of .fn-gantt .today (line 130 of style.css), so today does not highlight if today is during the weekend.

Good catch, added to the current milestone.
