[SUGGESTION] Add support for PWA

[zurdala]

I think it would be great to add the possibility of using this as a progresive web app
In my case, I access the transmission remote UI from my ipad and my phone, so adding the possibility of "Add to homescreen" or "install this app" would be awesome (specially for the first case)

Here are some resources that I found:
https://developer.mozilla.org/en-US/docs/Web/Progressive_web_apps/Installable_PWAs
https://developer.mozilla.org/en-US/docs/Web/Progressive_web_apps/Add_to_home_screen
https://dev.to/zvakh/a2hs-how-to-add-the-pwa-to-home-screen-27c4

I don't know how difficult this would be, but I think this could ease a lot the use of transmission remotely, and it would make Combustion look as a native torrent client!
I would contribute with this, but I'm no web developer

Also, it would sort of address the point "Installable Desktop app (Combustion-Remote)" in your Roadmap :)
