KDE Applications 17.04 beta packages available

[Albert Astals Cid]

Couldn't compile lots of pim packages because my build server didn't have 
qwebengine, but i trust CI in that it's fine.

The rest compiled fine.

ktp-text-ui wrongly requires Qt 5.6 instead of 5.7, will be fixed for RC.

I'll put up the "public webpage" announcement later this evening.

https://community.kde.org/Applications/17.04_Release_Notes contains notable 
changes, says NOT FINAL because i want to give it another read this evening 
but i think it should be almost complete.

Cheers,
  Albert
