adjust functor to move by dfa so that we cannot go to the last char of the file if (last char is a newline and is preceded by a non-newline), but otherwise we can go to the last char of the file.

in NormalMove.moveToLine function, use new LineGap function, 'LineGap.lineNumberToIdx', to get the index a line is at, and delete the Cursor.getLineStartIdx' function which we no longer need, as that functionality is in brolib-sml itself.

fix bugs in vi-l-dfa (we want to stop looping when the counter is ~1, because the starting character will likely be final/a not-newline, and we want to loop at least once; also, we want to special case 'twoNewlineState' as a final case which causes us to go backwards by 1 instead of treating 'oneNewlineState' as a final/special case). We also modify other code to use the new vi-l implementation in the program.
