[Qt-creator] Dev: Qt Creator 4.5 branch created

[Eike Ziller]

In preparation for the feature freeze of Qt Creator 4.5 (*), I’ve created the 4.5 branch from master.

Please start targeting the 4.5 branch instead of master. A final merge from master to 4.5 will be done next week after the feature freeze, so your open changes for master that you submit until then will also automatically end up in 4.5.

Br, Eike
