THRIFT-543. java: Generate normal style java files should respect the "optional" keyword when serializing 

As the summary suggests, this patch causes "optional" fields to be skipped if they are unset, even if they are primitives. As this patch is for the non-beans style generator, the user is expected to maintain the set/unset status themselves.
