Marty Schoch ee17941f7f switch DateRangeQuery to use time.Time instead of string 
as we are a Go library is this the much more natural way to
express such queries.

support for strings is still supported through json marshal
and unmarshal, as well as inside query string queries

as before we use the package level QueryDateTimeParser to
deterimine which date time parser to use for parsing

only serializing out to json, we consult a new package
variable: QueryDateTimeFormat

this addresses the longstanding PR #255
