Add 'check for update' option

[sa666666]

This will depend on having the infrastructure in Stella to do network connections. And that would have to be cross-platform too. Currently there is nothing here whatsover to do this. And nothing in C++14 to do it either, so we'd need a 3rd-party library of some sort.

Technically this is possible. But realistically, adding such an infrastructure just to check for updates is probably not feasible given our time constraints. However, people have also requested network play over the years, and if that ever happens, then we will have the infrastructure there to do this easily.

How about using SDL_net?

We would only have to check if the version number is lower and then open Stella's download website via SDLOpenURL;

Alternatively why might be able to check via web browser:

• Stella could either simply link to the download page and let the user check.
• Or Stella could send the current version as parameter for the link and the website would check it vs. the latest version. And offer a download if the latter is newer.

Of course this is less elegant than using network connections from within Stella.

With the PlusROM backend network communication working, an automatic check seems very possible.

@thrust26, don't we already have this in the Help Dialog now? So this issue can be closed?

[thrust26]

I meant something automatic, which notifies the user.

OK, no problem.
