Read utf-8 config file
Program options can be given on the command line and via a file called musiccollection.cfg. The last is necessary because it is really difficult to supply command line options on Windows with non-ascii characters.
The following tasks need to be done:
- Document how to create a musiccollection.cfg file
- Make it possible to supply a config file with a different name on the command line, i.e. mix command line and configuration file options
- Read a config file that is UTF-8 encoded
