[kde-edu]: ExtDate license problem

[Jason Harris]

Hello,

I have been planning to migrate away from ExtDate, to be replaced with 
KDateTime.  I was going to postpone this until after the 4.0 release, but it 
looks like I'll need to do it now.

The code in extdatetime.[h|cpp] is modified from Qt 3.x QDateTime sources, so 
it is necessarily licensed under GPL v2 only.  This is incompatible with GPL 
v3, to which KDE is migrating because of upstream libraries (so I gather), 
among other reasons.

KStars is the only program still making use of ExtDate stuff[1], so once I 
migrate to KDateTime, I can 'svn rm libkdeedu/extdate'.  The only regression 
is that users will not be able to set the date to before year -4712 (with 
ExtDate you could go back to -50000 or so).  Probably, almost no one will 
notice, and this can be re-extended in KStars for 4.1.

Objections?  Discussion?

regards,
Jason
