Read stdin

Tried a few different times, copying code from different places. Didn't
quite get it figured out at first.

Wanted to add STDIN lines to a string. Got that working with option 3,
but that `push_str` didn't appear to preserve newlines.

Ended up using this solution from StackOverflow:
http://stackoverflow.com/questions/13579266/how-to-read-user-input-in-rust/36374135#36374135

It adds the lines to a vector instead of a single string. Printing each
line individually then gives us out newlines. This way is probably nicer
also for getting the first line that starts with "From: ".
