Title: Implement String.to_hex/1

I've seen a couple of people ask about this in IRC, so this is a first stab at a solution for easily converting a string to it's hex representation. I did a bit of testing and comparison against the results generated by [this page](http://rishida.net/tools/conversion/). Let me know if you see any errors or other conditions to test for.
