Edit context menu appears only for utf-8 files in project explorer

[tsadowski]

Description of your problem

I created a new project from an existing folder. Some .py-files in the Project explorer had an "Edit" context menu, others only an "Open" context menu. Drag and drop into the editor would also not work.

A short look in the sources revealed that in explorer.py line 261:
def create_file_manage_actions
only utf encoded files are accepted as editable.

I have no problem with this behavior but it should be easy to find in the documentation.

What steps will reproduce the problem?

1. Create a .py file with ANSI encoding and try the context menu

An easy one for you @rlaverde :-)

I can't reproduce this. @tsadowski, could you send us a simple file that's failing for you?

Don't worry about it, I found how to reproduce this error.
