Merge lp:~haggai-eran/nuxcodesamples/widgetfactory into lp:nuxcodesamples

[Haggai Eran]

Introduce a widget factory example program modeled after Gtk's twf program.

Hi,

I wrote this patch to continue working on right-to-left support for Nux. I understand from the last interaction on my merge proposal (https://code.launchpad.net/~haggai-eran/nux/rtl-logical-packing/+merge/103818) that we need to work with Unity designers to decide on the best ways for supporting right-to-left languages. To do that, I thought it would be nice to show a mock program that uses as many widgets of Nux as possible (similar to Gtk's widget factory), and show the designers how we expect that program to look under a right-to-left locale.

In this patch I wrote such a program. I wanted to get Nux developers feedback on it. Does it contain all the interesting widgets in Nux? Are there any missing widgets, or widgets that are used incorrectly?

Thanks,
Haggai Eran

Enable right-to-left mirroring depending on locale, when RTL support is available.

Use ScrollView instead of separate scrollbars in twf.
