Add more diverse license support

[TheSlowGrowth]

More types of license

It would be great if projects could add more licenses. Examples:
GPL, LGPL, MIT, Apache
Some projects might have a custom license (midibox for exampe). Muzhack should add options to add custom licenses or have an option that says: "For license: see description"

multiple licenses

Some projects use different licenses for different parts of the project (e.g. software/hardware). It would be cool to be able to add multiple licenses.
