Eliminated two members of the osrfMessage structure:

Eliminated two members of the osrfMessage structure:
result_string and sender_tz_offset.  Neither is used for
anything, and either may be easily reinstated if necessary.

I was tempted to eliminate the protocol member as well,
since it isn't used for anything either.  However it's
populated from one of the parameters to osrf_message_init().
Getting rid of the protocol member properly would ramify
to all the code that calls osrf_message_init(), which would
be a lot of work to undo if necessary, so I left it alone.
