NSTimeZone bad OS_API_VERSION macro

[Luboš Doležel]

Hi,

GNUstep's NSTimeZone.h surrounds a group of methods including 
"secondsFromGMTForDate:" with

#if     OS_API_VERSION(GS_API_MACOSX, GS_API_NONE)

This makes these methods invisible (note GS_API_NONE). I think it should 
say GS_API_LATEST.
They are implemented in Base, so I suppose hiding them wasn't intentional.

Then there is a comment "Not implemented" above 
daylightSavingTimeOffsetForDate, but this method is actually implemented.

nextDaylightSavingTimeTransitionAfterDate is not implemented, so the 
comment is correct in this case, but I'll fix that soon ;-)
