Tutorial should mention arrays

[KamilaBorowska]

After somebody came to the IRC channel asking why her function (using $argv[0]) doesn't work, I think that it should be mentioned in the tutorial, especially considering they do start with 0 in bash, with "unlike other shells" wrapper to make it more noticeable (even if it's just bash, zsh does it just like fish shell).

We do, except we call them lists: http://fishshell.com/docs/2.1/tutorial.html#tut_lists

We should maybe include "array" in there somewhere so that someone searching for 'array' will find the lists section.
