In-program editor

[darvin]

We need in-program editor (not for replace of shell) with functions
Open
New
Save
Run
for Object Oriented mode. Also, when program in editor runs (or news, or opens) we need reset python shell and turtlewidget

after #60

i think it is enough complicated feature, so we should split it to two independent pieces and nominate them to google-code-in

(Sorry for not commenting on this, I somehow missed it.)

Sounds good. We'll work out the specifics after the 0.2 release.

We should maybe aim for a simpler solution (not trying to copy what IDLE already does). This could be:

1. Provide a "Show commands I typed" that would pop up a text window with all commands typed since PythonTurtle was opened.
2. Naturally, users sould be able to copy the text from that text window. Maybe also allow them to change everything to their liking.
3. Allow users to save the text to a Python source code file.
4. Provide a "Load commands I typed" feature that would load a Python source code file and run it. (That sounds scary! 😏)
