[Joern Ungermann]

Ideally the program should look similar to

mslib/mswms/mswms.py

with mostly argument handling and the functionality should be somewhere else (for better testability).

[Reimar Bauer]

Added version/debug switches and logfile redirection to mscolab

minor refactoring, renaming of global app to APP, fixed tests.

Fix issue #493
