Show all transactions in a block

[mikedotexe]

During rapid development, I hardcoded [0] in a couple places, including the transactions.

So if you execute two transactions it'll only show one. We just gotta make it actually loop and stuff.
Also, I would really like to keep in mind that having useful snippets other people can borrow is great. So it wouldn't hurt to keep track of a little cookbook of recipes on how you do stuff. (Ex: take an ugly public key and decode it into something. Or take an ugly signature that has bytes and base64 it so the whole thing is readable, that kind of thing)
