Runs .each successfully, suggests how to use with no cljs changes

- Refers to the new text getting function.
- Function name changed to getAllText().
- ALSO, row #1 doesn't get it's number at the beginning because
I got rid of updateNums, or whatever, in the main js file. Have
to add it in to the creation of the first row.
Finds textareas more flexibly, any parent can be used

- Though you have to be careful what parent you use. If you have
multiple text areas and you use the body as the argument, you'll
get all .text-row's in the body.
- Is this better or worse?
Actually, gets just .text-row's not textareas
*Now* it gets all the textareas in a parent
Returns the expected values. To me.
Adds editor.getValue() that takes a $ collection

Damn, maybe it's meant to take a DOM element. We'll find out...
