Add the ability to style RadCarousel via Visual Style Builder.

To reproduce: 
1. Open ThemeViewer 
2. Choose theme Desert 
3. Check View RTL support
4. Check 'Aero mode on' of ribbonbar & backstageview, after that click on 'show form' button
5. Check 'Aero mode on' of RibbonBar & Office2007 App Men, after that click on 'show form' button and will see that ThemeViewer crash
When set theme Desert and change values of the properties of RibbonBar in the VisualStyleBuilder generate the same error.

The Text and Image Primitives of RadButton are not exposed in VSB

FIX. VSB - error when trying to preview a theme in ThemeViewer and the current directory is different

Open Package Windows7.tssp - RadPageView - RadPageViewStripElement - StripViewContainer - StripViewButtonsPanel - LeftScroll.  Edit Repository Item StripLeftArrow.  Click inside Image property to highlight - Unhandled Exception.

Telerik Metro theme is not exported by VSB

If you load a layout where there are horizontal splitters, you will notice that their theme is not correct.

Implementation of the new Visual Style Builder.

Add "Design View" and "Preview" tabs in the View menu of the Visual Style Builder. Currently you could hide them by clicking the scroll button and there is no easy way to restore them

If you pick a font in the style builder that doesn't have a 'normal' setting (like a bold-only font) the VSB will crash.
