[Kst] Qt5 binaries for Windows

[Nicolas Brisset]

Hi Peter,

> Kst with Qt5 could be downloaded from github:
Well, that sounds pretty interesting. I'd like to do some tests, but I haven't figured out how to download that file.
Could you give more precise instructions, or upload it under snapshots/ on the sf.net page?

When I get my hands on it, I'll do some performance tests and let you know how it behaves.

Nicolas
