Make studio update file in editor if file has been changed on disk

[evsey9]

Currently, if an open file has been updated by a different IDE, the editor will give you no warning, gladly overwriting any changes you've made in the different IDE if you forget to re-open the file and save at any point.

Proposal: when studio detects a file update, show a prompt that lets the user choose between overwriting the file in editor with the version on the disk, or keeping the version that is currently in the editor. Along with that, the prompt could also have a "Show difference" button, showing difference between disk and editor versions.

BTW, it is preferable to use simulation engine as an external tool with 3rd party editors. Any reasons to use TS? (RUS) https://help.trikset.com/integrations/vscode/run-2d-from-vscode
