Editor Update

[jmwright]

Spyder has been significantly refactored in version 6, and as long as we are on 5.x the upgrade path to Python 3.13 and beyond is challenging. Rather than refactor CQ-editor to fit Spyder 6, I took a shot at implementing a custom editor. It does not have feature parity yet (breakpoints are not implemented), but it does work for basic tasks, and I think the path to a replacement CQ/Python editor is straight-forward.

Now would be a good time to give feedback about this editor. The idea is to reach feature parity with the Spyder IDE (as we use it, not everything Spyder can do) and then include this editor in the next release.

A few things to note:

• Breakpoints and most debugging support have not been implemented yet.
• The syntax highlighter is tuned for a light theme, and is currently a little hard to read with a dark theme.
• When running this branch you will see some messages in the console about methods that are being called. These are some of the methods I am aware of that have not been implemented yet.

Much of the Qt editor code has been adapted from here.
