"None" is a reserved keyword for Python binding

[klayoutmatthias]

A specific issue is "pya.Cursor.None" which is not available on Python.

See https://www.klayout.de/forum/discussion/1357/pya-cursor-none-bug#latest for the related discussion.

The issue is more generic - "None" is used in other places too.

So the solution is better to provide a Python-compatible alias with "" appended (as done with "exec" for example): Use "pya.Cursor.None".

Will be released soon with 0.26.1
