Support or disable installation as Progressive Web App

[teusbenschop]

It was noticed by @warpok that Bibledit nowadays can be installed as a PWA - progressive web app.

This issue is for looking into this whether this is supported for Bibledit, or whether it should be disabled.

Till now it has not been tested, and running it is for not guaranteed to work as expected.

I want to just give my comment, from what I have seen, not from a technical point of view.
When a PWA (like from Scripture App Builder) gets installed as a PWA, then it is given an icon on the desktop, then when it is activated by that icon, the browser host does not display the other tabs and the address bar. This saves one line, (the address bar). The title bar for the PWA is displayed replacing the display of tabs.

The Chrome browser creates an icon without identification as coming from Chrome, but the Opera and Brave browsers (and probably most others) will have a little browser icon on top of the Bibledit icon on the desktop. When opening the browser from its main icon, then the PWA is still found as one of the tabs.

If that's all a PWA does, then I recommend not disabling it.
