Error popup on 'Help' > 'Equation Summary'

[dracorpg]

Trying to reach the equation summary shows an error popup instead.

To Reproduce

1. Click on 'Help' menu > 'Equation Summary'

Expected behavior
The PDF file with equations should be displayed :)

Screenshots
I'll dispense with an actual screenshot, it's a relatively bland error popup that reads:

A JavaScript error occured in the main process

Uncaught Exception:
TypeError: require(..).shell.openitem is not a function
at click ([PTree]\resources\app.asar\main.js:211:41)
at Menultem.click (electron/js2c/browser_init.js:73:1683)
at Object.a._executeCommand (electron/js2c/browser_init.js:81:2343)

Desktop (please complete the following information):

• OS: Windows (also confirmed on Fedora)
• Version: 2.0 (seems to be a regression from 1.8)

Thanks !

shell.openItem() is no longer a function since Electron v9.0.0. A fix has to be found to open an external file with the default program. shell.openExternal() may be a solution.

For information, on Windows, the PDF file is located in the root folder of the application.

From a cursory glance at the Electron doc, shell.openPath() looks to me like the most direct replacement for shell.openItem()
... and actually, 9.0 API breaking change notes say it's precisely the case: https://www.electronjs.org/blog/electron-9-0#api-changes :)
