Allow Editing of .gx files via the built-in text editor #3
Description
The GraphEx UI allows you to edit any type of text file but '.gx' are loaded as graphs. This is still the default behavior we want, but we should also include a right-click option to edit the yaml files (.gx files are yaml) in the text editor.
This can be very useful in some edge cases where the yaml could become malformed. In the past, there have been some bugs that can cause the yaml to not format properly. As of right now, you would have to use a separate text editor to open the .gx files to fix them.
