Add a script "idles" which opens a Python Shell window.

The default behaviour of idlefork idle is to open an editor window instead
of a shell. Complex expressions may be run in a fresh environment by
selecting "run".  There are times, however, when a shell is desired.
Though one can be started by "idle -t 'foo'", this script is more
convenient.  In addition, a shell and an editor window can be started
in parallel by "idles -e foo.py".
