src: switch from Qt to boost implementation of executeProcess (#1145)

* changed implementation of executeProcess
* unified all different implementations of executeProcess
* separated arg list from command for all calls of executeProcess (this also required to remove quotes that were added to path args because otherwise the Python indexer would mistake absolute paths for relative paths.)
* update expected output for custom command tests
