* Event attribute filtering is overly aggressively (#86)

If you try to create a custom attribute with a value of 0, our event
serialization code would filter that out because `0 != null` is false.
However, it is reasonable to expect that a user might want to provide
the value of 0 as a custom value.

The code has been updated to only exclude explicitly null values.
