Fix for #218 - Check empty namespace in general generator

If you have a schema with no namespace, the resulting C#/Java won't have
an erroneous empty namespace keyword.

Normal behavior is to not output fields that happen to have
the default value, since those will be reproduced anyway
when turned into a FlatBuffer binary. This however can be problematic
when using JSON to interop with other system since they might not
know this default value. This flatc option (and also flag
to GenerateText) will force those fields to be output anyway.
