remove mixing enumerable into string

[kbrock]

AwesomeSpawn is throwing errors for me because we mix Enumerable into String.
Infinite recursion nasty stuff.

@jrafanie suggested it was time to remove this crutch?

I ❤️ this. We should blow up if we're still doing ruby 1.8's String#each

Everything looks good. 🍪

@jrafanie I also noticed that String.ord is available in rails up to 4.0.2. didn't look too hard into that.
Do we want to add deprications? rails-doc

Yay!!! Thanks for cleaning this up.

String#ord is a possibility, not sure though since we might use that in a non-rails context in the smartproxy or elsewhere. We can certainly deprecate it though.
