refactor commands to take dynamic translation descriptions

[proddy]

    > Yes i think this works, but i don't like to register only the translated fullname to command. If you later change language the translation of registration stays. It's a bit more work and need some more translated words for system and dallas commands, but it's cleaner to to have Command::add with the complete fullname-list and translate in Command::show() etc..

yes I agree, the translations should be dynamic like the rest of the code. It was a design principle I started with when writing the translation code so just forgot this. I'll see if I can implement it tomorrow
