bug#65253: Renpy-launcher raises exception when opening editor.

[Jesse Gibbons]

Here's a problem I diagnosed in the version of renpy installed by guix 
(hash 19a7a824c35eae56ce56e2a460042fb7e2129234):
Problem: Editor won't open, raises exception.
How to replicate:
1. Run renpy-launcher
2. Click any of the files under Edit File.
An exception is raised and the stack trace is dumped.
Cause: Editor files (*.edit.py) are not copied at install.
Proposed Solution: Copy editor files at install. I frankly don't care 
about Visual Studio Code or Atom, but at minimum "launcher/None.edit.py" 
and "launcher/System Editor.edit.py" must be included or the editor 
function won't work.

bug#65253: Acknowledgement (Renpy-launcher raises exception when opening editor.)

It turns out 'Visual Studio Code (System).edit.py' is required to fix 
this. I recommend a patch that removes the Visual Studio Code (system 
and 'official') and Atom editor options, but that could be just my own 
preference. Please do not remove the None or System Editor options.

Until a patch is sent to fix this issue, concerned users may work around 
it by creating a directory in the configured projects directory and 
copying 'None.edit.py', 'System Editor.edit.py', and 'Visual Studio Code 
(System).edit.py' from the source into that directory. 'Visual Studio 
Code (System).edit.py' can contain the contents of either of the 
alternatives.
