Incorporate friendly-traceback into a modified version of IDLE

[aroberge]

To facilitate the integration into other projects, I want to create a demo where I do so, and possibly document the steps taken in a series of blog posts. After a few experiments, I have decided to use IDLE as a base editor and use monkeypatching to incorporate friendly-traceback.

• The invocation will be done using --idle as a command line option

IDLE itself has many command line options. This demonstration should support the following

• by default, it should open a shell window (-i in IDLE)
• if -e is specified (together with --idle), it should open an editor instead [same flag as IDLE]
• if a source file is specified (together with --idle), it should run this file in IDLE's shell [similar to -r file in IDLE]

Some additional features

• Ability to change the language via a menu in IDLE
• The "friendly" output shoud be shown in a separate window, with custom formatting.

Closing this issue as it appears that a simple patch to IDLE is not as straightforward as I first thought it would be. I believe it is more important to focus on trying to make Friendly-traceback as complete as possible in its coverage of Python exceptions, and having this issue open is just a distraction.
