[TIMOB-16782] Window refactor and extras

[pec1985]

Refactored:

• Ti.UI.Window
• Ti.UI.AlertDialog
• Ti.UI.TabGroup
• Ti.UI.Tab

Fixed:

• Events on Window, TabGroup, and Tab - open, close, focus, and blur
• AlertDialog was not getting garbage collected
• Garbage Collection - App would crash randomly when GC kicked in.

Something is wrong with the setters... TableView.setData, Label.setText all crash with not a function error. Strange though because it works enough to load some data but as soon as you start navigating a few screens it pops up. Using the latest in Master though I have no issue.

I can reproduce that like so:

var masterWindow = Ti.UI.createWindow({
    title : 'Master Window',
    barColor : '#000000',
    backgroundColor : 'green'
});

var tabgroup = Ti.UI.createTabGroup();
var tab = Ti.UI.createTab({
    window: masterWindow
});
tabgroup.addTab(tab);

tabgroup.open();

var btnOpen = Ti.UI.createButton({
    title : 'Open'
});

btnOpen.addEventListener('click', function() {

    var detailWindow = Ti.UI.createWindow({
        title : 'Detail Window',
        backgroundColor : '#ffffff'
    });
    var label = Ti.UI.createLabel({
        width: 300,
        height: 30,
        text: 'Hello'
    });
    detailWindow.add(label);
    detailWindow.addAction({
        title:'here',
        callback: function(){
            label.setText('Hello World');
        }
    });

    tab.open(detailWindow);
});
masterWindow.add(btnOpen);

And then clicking twice on the action item. Try using the property setters/getters instead of methods, i.e.: label.text = 'hello world';
