Fix week and month Time grain in MySQL (#297) 

With mysql datetime and timestamp columns, currently the Time grain "week" and "month" options don't remove the time part. This results in groupings like this:

timestamp count
2015-04-05 07:00:00 1
2015-04-05 10:00:00 1
2015-04-05 11:00:00 2
2015-04-05 11:50:00 1
2015-04-05 12:00:00 5
2015-04-05 14:20:00 1
2015-04-05 14:30:00 1

and so on.

This is solved by wrapping the DATE_SUB with DATE().
