[QBS] FYI: Branch 1.7 created

[Christian Kandeler]

Hi,

we have created the branch for the 1.7 release of qbs (tentatively
scheduled for December) today.
Contributors should push bug fixes and low-risk improvements to this
branch; other changes should target the master branch.
Users are encouraged to test this branch against their projects, so
possible bugs are found in time for the release.

Christian
