RFC: addition of generic timezone support to kdelibs

[Shaheed]

Hi,

I just committed the first version of KTimezones to kdelibs, and ported 
kicker's clock applet to use it.

As a result, I hope that non-glibc systems such as Solaris should now have 
multi-timezone support for the clock, though the correct country flags won't  
be shown (both the country and latitude/longitude info are missing on 
Solaris). I have not actually been able to test it on Solaris, so problem (or 
success) reports are welcome.

I'll write when I pick the next porting victim.

Thanks, Shaheed
