[pacman-dev] permission/location for var/abs and cache/src

[Andreas Radke]

we still preset the values to /var/abs and /var/cache/pacman/{src,pkg}
but recommend to use an unprivileged user for all that 
packaging stuff.

this forces everybody to lower the directory permissions or raise the
user up into a certain group or even give sudo permissions.

i think adding a new group "packager" holding these directories could
solve that.

various options are possible. what's the best and most secure one?
