QSF app improvements

[zbranzov]

iOS:

• [ ] In About page change Telerik to Progress Software
• [ ] In Reservations example Table details cannot be changed- No choices appear in the wheel.
• [ ] In Item reorder example the icon in the button when swiping item left/right is not centered.
• [ ] In Selection example if you swipe an item left/right a few times, the app will crash. Just open the example and swipe. Also, you cannot change favourite items not sure if it is intentional.

Android:

• [ ] In About page change Telerik to Progress Software
• [ ] Home and About side drawer buttons look strange, "What's new" button exists but not in iOS and buttons don't work.
• [ ] Examples' menu buttons styling and Example information page styling seem strange.
• [ ] Bar series, Line, Area, Pie series examples crash the app.
• [ ] Selection example tabs are not styled well.
• [ ] In Selection example if you swipe an item left/right a few times, the app will crash. Just open the example and swipe.
• [ ] In Selection example cannot exit Edit mode. In Edit mode, clicking the first items crashes the app also you cannot change tabs when editing.
• [ ] In Reservations example changing a reservation or adding a new one is not reflected in the UI.
• [ ] In Item reorder example the icon in the button when swiping item left/right is not centered.

One more major thing:

The app crashes in Android after the following:

1. Go to selection example
2. Tap edit button
3. Tap back button

Error is:

System.err: com.tns.NativeScriptException:
System.err: Calling js method onBindViewHolder failed
System.err:
System.err: TypeError: Cannot read property 'nsView' of null

This happens while using "nativescript-ui-listview": "~6.2.0". With "nativescript-ui-listview": "~5.0.0", this is not reproduced

Above issue is fixed in tbozhikov/clean-ups branch of QSF and nativescript-ui-listview@6.4.1
