[Qbs] Branch 1.22 created

[Christian Kandeler]

Hi,

we branched off Qbs 1.22 today. Scheduled release date for
version 1.22.0 is end of March (together with Qt Creator 7.0).
We recommend users to try this branch with their projects and report back any
new problems they find.
Contributors are requested to push bug fixes and small, zero-risk
improvements to this branch, while features continue to go to master.
Patches currently under review can be moved if they are reasonably close to
finished.
