[IMP] web: use moment object instead of string for date

Before this commit, the odoo web client used strings to represent dates.

Now, the date is parsed into a moment object when the value is read from the
server side. The widget formats the object to display the value. When the
widget value changes, the value is parsed to a moment object. The value is
automatically formatted to server value in ajax calls (toJSON method).
