[kde-edu]: [RFC] removing ExtDate

Since Qt 4.x, QDate now allows dates over a much wider range of years (-4713 
to 11,000,000 rather than 1582 to 8000).  Because of this, it could be argued 
that there is no longer a need for ExtDate, although it does provide for a 
different range of years that extends further into the past (-50,000 to 

Is there any reason to keep ExtDate?  In KStars, I actually derive my own 
KStarsDateTime class that adds some astronomy-specific things, so I'd be 
prefectly happy adding the ability to use dates prior to -4713 to 
KStarsDateTime, and using KDateTime as my baseclass instead of ExtDateTime.

A quick look at lxr.kde.org shows that only KStars and Kst are using 
ExtDateTime, so I'm especially interested in hearing from kst developers.  
Although, it looks like they've forked their own version of ExtDateTime, so 
maybe they don't care what we do in libkdeedu :)
