Follow-up on previous commit: Generalized the "Command" key support, it compiles on all platforms and somebody may want to plug a Mac keyboard in a PC :)

Added a "command" symbol in the fonts, so shortcuts that use this key can be displayed.
Fixed: In Keyboard settings, some very weird keys (Thinkpad "volume up") were displayed with a wrong number.
