Comments aren't handled at all

[wasamasa]

If I run the REPL and enter ; test, it hangs and doesn't proceed to the next prompt. I'd expect the input to be ignored (as the tokenizer yields zero tokens in this case and there's nothing useful you can do) and the next prompt to be displayed. Worse, if I run iris test.lsp containing comments, nothing is evaluated at all and the interpreter exits with 0, as if everything is fine.

Installed via go get github.com/asciian/iris on Arch Linux.
