OSMF SVN

* Unbinding chrome font and visuals from the ChromeLibrary project,
* Introducing asset loaders, that can load imagery and fonts either from file, or from embedded tags,
* Introducing AssetsManager, a class that loads a set of assets, exposing loaded assets by a string identifier,
* Introducing a number of 'resource' classes, used by assets loaders to determine the type of asset to load,
* Introducing a number of 'asset' classes, used by assets loaders to export their loaded content to, as well as by widgets to reference an asset.
* Introducing AssetsParser, a class that translates XML formatted assets definitions into a set of resource classes.
* Introducing Scale9Bitmap that allows usage of a scale9 rectangle on bitmaps,
* Changing all widgets to be LayoutTargetSprite derived, enabling them to be laid out using the OSMF layout APIs.
* Extending Widget with child management functions, allowing any widget to have children.
* Introducing WidgetsParser, a class that translates XML formatted widget definitions into a set of Widget classes.
* Introducing Configuration, a class that loads an XML file that contains asset- and widget definitions, and sets up an assets manager if so desired.
* Updating both OSMFPlayer and ControlBarPlugin projects to provide their own chrome visuals and fonts using the new configuration system. OSMFPlayer uses run-time asset loading (meaning that all assets are to be uploaded to server alongside the player SWF), and ControlBarPlugin uses embedded resources.
