Describe the bug
Although I only saw it here:
https://github.com/jamulussoftware/jamulus/blob/master/src/serverdlg.cpp#L159-L165

Probably there are still places throughout the code where Jamulus, not the APP_NAME variable is used. This makes the unlikely change of renaming the software more difficult

To Reproduce
/

Expected behavior
Use a parameter everywhere (%1 is being used instead of: Jamulus is being used) and let it be filled by the APP_NAME constant.
