All pretty much throw away code, but it makes something you can type in
backspace... time to stop wasting time
String based rope class added.
Crappy balance now in place (and insert now actually works.)
Added row_bounds functions that allow many lines to be discovered in one go - will cut out extra linear searching for common editor refresh tasks
last throwaway change set on the old stuff... maybe
