WiPy support added and weight reduced
A port for WiPy was added. That caused a re-thinking of the function set. As part of that, I dropped some of the nice-to-haves, to get as many useful functions as possible available on WiPy. Changes:
- Support for WiPy
- Dropped context sensitive behavior of Tab, Backtab, Backspace and Delete
- Left and Right skip over to the next line, if needed
- In the Linux/CPython version window resize triggers Redraw.
