[arch-general] virtualbox additions package naming

I've been criticized a lot because I choose poorly the name for guest additions. Right now the packages are like this: virtualbox-addtitions - contains the iso with guest additions for linux/windows/etc and is installed on host virtualbox-guest-additions - contains guest additions only for an arch linux system as guest. virtualbo-guest-modules - modules only for an arch linux system as guest. Now that virtualbox 4.1 is released I need help choosing this names. -- Ionuț
