wmix: be more verbose about the configuration file in use

Browse source 
If the config file was set by user with '-f', it would be a good idea to
report him if we're not able to load it.
Took opportunity to report to user that the config file is loaded if he
asked for verbose operations, so he can see if the default file loaded
is the one he expected.
