KDE Frameworks 5.1.0 release

[David Faure]

I just tagged and packed 5.1.0.

Main changes:
* KTextEditor: Major refactorings and improvements of the vi-mode
* KAuth: Now based on PolkitQt5-1
* New migration agent for KWallet
* Windows compilation fixes

* Internationalization fixes
* New install dir for kxmlgui files
* A number of bugfixes

k-f-d: anything to add?

If changelogs in announcements are useful, then we should start using 
ChangeLog lines in commits like Qt does, it would save me time digging into my 
email archive and trying to summarize series of commits...
