Use TARGET name for run configurations

It would be useful to be able to give descriptive names using QMAKE_PROJECT_NAME, which is currently only used for vcproj? For instance, qtquickcontrols/tests/auto/controls/controls.pro could contain "QMAKE_PROJECT_NAME = tst_controls" and it would then appear as "tst_controls" in the list of run configurations (and in the project tree).

Qt Creator uses (mostly?) the base name of the .pro file for naming run configurations. This often leads to name clashes. Perhaps it would be better if Creator used TARGET instead. See the attached screenshots.
