Started some work on Helpers

You might need to look over some of the stuff with forms and helpers. I wanted to add a full example with Bootstrap because so many newcomers seem to be confused as to how to integrate it. Also, I wanted to add a <select> example because, again, a ton of people seem to be confused on how to do this right (and please correct my code if I'm wrong!).

Also, as mentioned before, I think Forms are a subject by themselves, and might need its own section, but that is your call.
