[Qbs] 1.15 branch created

[Richard Weickelt]

Hi,

Christian has branched off qbs 1.15 yesterday. Scheduled release date for
version 1.15.0 is end of November (together with Qt Creator 4.11) [1]. We
recommend users to try this branch with their projects and report back any
new problems they find. Qt Creator 4.11 beta still ships the Qbs 1.14 branch
and will be updated early next week. Snapshots can then be obtained from [2].

Contributors are requested to push bug fixes and small, zero-risk
improvements to this branch, while features continue to go to master.

Patches currently on gerrit can be moved if they are reasonably close to
finished.

Richard
