The date validation is throwing error.

[Genie]

When you input a task as macro syntax, the date validation is throwing error.

if you input as below

{{{#!Gantt id="3124d31e34b0" style="blue"
Design db schema, , 2014-08-00, , 
}}}

the date validation is throwing error.

"2014-08-00" is an invalid date, or the date format is not known. Try "YYYY-MM-DD" instead.

and then it cannot be edited forever.

This is patch for that.
