Change from WebsiteBundle to AppBundle

[webmozart]

In order to more closely reflect Symfony Standard, "WebsiteBundle" should be changed to "AppBundle" in Sulu Standard.

When working on the WebsiteBundle we could maybe also reduce the code in there, e.g. #593

[sagikazarmark]

Is it actually necessary? Views could just be moved to the app/Resources directory. If the controller gets moved to somewhere as well, maybe the whole bundle become unnecessary.

[danrot]

@sagikazarmark You are having a good point here... I'd say if we solve #593 it would be easily possible to remove the WebsiteBundle completely.

[sagikazarmark]

Sounds like a plan.

[danrot]

@webmozart #593 is solved, and in sulu-minimal we don't have a WebsiteBundle or any other bundle at all anymore. Is that issue solved for you with these improvements?

[sagikazarmark]

What's the difference between sulu-minimal and sulu-standard?

[danrot]

@sagikazarmark sulu-minmal is much slimmer than sulu-standard, and has a few other improvements in it (Symfony3 folder structure, easier to setup, ...)
