Add null as option to NumericFilter

[wizhippo]

Currently, when using the numeric filter there is no way to specify you want null.

You can use the NullFilter but you can't use both at the same time.

I ran into a similar problem with DateTimeFilter and I think it's more of a bug.

If I turn on the filter and compare whether the value is empty (null), it executes a database query with entity.propertyName = null instead of the correct entity.propertyName is null. And likewise for not equal, != null instead of IS NOT null.

Hello, sorry for digging up this old issue, but has anyone found a workaround for this?

Thanks!
