[IronPython] seperate output

[Kamil Dworakowski]

Resolver One recalculations happen in a runtime, each recalc in a
seperate ScriptScope.

I am tinkering around adding an interactive shell (sth like python
interacitve interpreter) with access to the last recalc scope. This is
a window with two text boxes, one for input and out for output.
Ideally it would display only the output from the issued commands
there, and they shouldn't go to the 'output pane'. I am currently
using code.InteracitveShell inside the same runtime as the recalcs are
happening, and of course the command results go to the 'output pane'.
Any ideas on how to achieve that?
