Better CLI

[sezanzeb]

I was having trouble with the command line interface, mostly due to missing features.

So I set up some directories containing files that should be converted with a subdirectory structure and worked on the soundconverter cli until I was able to convert them into a target directory.

added -i, -r, -Q and -o options:

• -r goes into subdirectories
• -i ignores files that have already been converted
• -o specifies an output directory in which the original file structure is restored
• -Q takes values between 0 and 5 and indicates the quality of the conversion

furthermore:

• removed --help-gst from help since it is not used
• added example usage to --help
• reduced redundancy of quality numbers in ui.py with get_quality in settings.py

in .gitignore was a path "src/soundconverter". This is something old and can be removed, right?

it would be good to have the flac compression rate and such things as command line args, but for now I guess it's already quite some improvement, maybe I'll add that later on.
