Create #alias method, callable on any object, _ by default.

Browse Source 
While I'm not a fan of making abstractions where a simpe solution
exists, I think this is good as it makes a public API for extending
underscore, therefore making it "ok" to make your own alias names.

Also give us some future proofing in case we ever add in hooks on
method definition. For example, right now if you add a method
or make an alias in user code, it isn't added to the wrapper prototype.

Added tests and inline docs, no external docs
