[REG 4.5 -> 4.6] Meaningless run configuration names for CMake project

1. Get the sources of Speedcrunch 0.11.
   I can send them to you if needed.
2. Open src/CMakeLists.txt in Creator.
3. Check the "Default" build configuration of a kit using Qt 4.8.
4. Click "Configure Project".
5. See the names of the available run configurations.
   They are just indexes.

The run configurations should have meaningful names, e.g. the names of the respective executable. This worked correctly in Creator 4.5.
