[PythonCE] New release (2.3.4)

The pcceshell is now something internal to python.exe -- less things
necessary to have a running Python Shell, so less things to go wrong.
It does specifically look for other versions of the Python Shell running
and resumes it.  I can add a command line switch that disables this.

> 2) There seems to be a problem in the error reports of the traceback for I/O

> IOError: [Errno 7] T: <file path>
> The "T" is not very informative.
> Similar  thing is with the WindowsError.

This is because there is no sys_errlist[] in the Python "C" runtime.  I will
see what I can do to emulate this.

> 3) Is there a way to add thing for when python starts up. For example I would

> os.environ['PYTHONDOCS'].

Will implement something for this as well.

> 4) There are also other changes that people made to the previous releases.
>    My question is if there is any way to incorporate them.
>    For example the exec* functions hadn't worked, Telion made a module
>    osce that made some work. (there were others also).

If these were external modules (i.e. they are .pyd or .dll files) then we should
be able to easily incorporate them.
