[whatwg] date/time and precision changes

Also a float slider is simply continuous... it effectively has no step 
value... I don't see how to specify a continuous float slider without 
having to say something hacky like step="0.001".  If you must have a 
step attribute, I think you should have a special value, continuous, to 
denote that the entire range of values is allowed.

This is another reason why I think the precision value was necessary.  
Both a float slider and int slider should by default be considered 
continuous, i.e.to support all possible values.  While a step attribute 
is definitely useful, I don't think it's intuitive to use it to set the 
data type of the slider control.  Logically the default value of step 
should be "continuous" IMO and precision="integer|float" should be 
supported to determine what "continuous" means.

Adding numeric values for step also introduces an ambiguity of how the 
slider should behave when dragging.  Does it jump in increments or does 
it smoothly slide and do rounding to the nearest step increment?  This 
is perhaps something for a CSS property to control.
