Implimented very basic typing ability

I've implimented some very basic typing ability, the ability to type on
one line and to delete back on that same line.
File Write

Set up the basic ability to write to a file. Currently this can be done
by pressing alt+s, though later it should be done using a clickable
control.
Working on moving cursor

Cursor moving code, currently not working.
Multi-line typing

Got multiline typing working with appropriate enter key functionality.
Backspace works on the current line, working on backing lines.
