Australian timezone configure option

Hi,

Being in Australia, it's always been a minor pain building the support
for Australian timezone rules by defining USE_AUSTRALIAN_RULES to the
compiler. Not to mention the not inconsiderable pain involved in pawing
through the code and documentation trying to work out why the timezones
were wrong in the first place.

This patch makes it a configure option - much easier to use, and much
more obvious for the other Aussies who keep wondering why their
timezones are all messed up...

Obviously 'autoconf' needs to be run after applying the patch.

Cheers,

Chris,
