Request: classic support for bbui.js

[MerrickZ]

for example.
when pushed a screen like "settings", press back button, it should execute "popscreen", but now it just minimized the app to background.
when press menubutton, it should open the app menu, but it did nothing.
this should be implemented.

[T-M-C]

you can easily assign your own function, like "popscreen" to the button:

document.addEventListener("deviceready", function () {
    document.addEventListener('menubutton', onMenuButton);
    document.addEventListener('backbutton', onBackButton);
}); 
function onMenuButton() {
    console.log("The Menu button was pressed");
}

function onBackButton() {
    console.log("POPSCREEN?");
}
