Move simulation execution from Makefile to Bash script; show Progress

Additional code is needed to show the progress. Otherwise Travis is
likely to become unhappy and terminates the job. This was no fun within
the Makefile. Moving the execution to a Bash script allows better
maintainability.
In case of an error the error all logs will be printed when using a CI.
