Currently, the MPF Spawner only looks for mpf.exe in the directories stored in the system PATH variable. If Python is installed at user level, which is the default setting in the Python installer, the Python scripts directory will be added to the user PATH and the MPF Spawner is unable to find mpf.exe. This pull request solves issue #15 by searching the user PATH variable as well.
