add support for custom templates of gantt elements

[Guria]

Would be great to define template for gantt element with binding to attributes of object.

var tasks = [{
    "startDate": new Date("Sun Dec 09 01:36:45 EST 2012"),
    "endDate": new Date("Sun Dec 10 02:36:45 EST 2012"),
    "taskName": "E Job",
    "status": "FAILED",
    "type": "Type A"
}]

could render on chart into something like:

Type A		Failed
09.12	E Job	10.12
