Cairngorm Code

* Adding a new view loader called 'ModuleViewLoader' specifically written as a custom Spark component.
It provide a separate skin based on 4 states (normal,loading,error,loaded). The Default skin is ModuleViewLoaderSkin

the ModuleViewLoader component benefits from new features such as external Loading Policy strategies.
The lib provides 2 Load Policy:
- BasicLoadPolicy: load module on addedToStage and unload on removeFromStage
- LazyModuleLoadPolicy: load module on demand based on the moduleId property of the message. As soon as a message with a corresponding moduleId is dispatched, the module is loading itself automatically.

* Refactoring the SDK3 ViewLoader to reflect the same features as the new Spark ViewModuleLoader except that the SDK3 ViewLoader do not include states to display different views as the Spark component does.

* Refactoring the ModuleTest sample project to use the new features/components

Fixed Parsley deprecation warnings to use 2.2.2 ObjectDefinition builder process.

Insync Refactorings, Module lib: Added missing parameters from IModuleInfo interface. Maven: Take Persistence out.

Migrating Cairngorm Libs to Flex 4. From now, the trunk will contains Cairngorm libs and samples targeting Flex SDK 4.0 however the maven build will continue to support Cairngorm libs targeting SDK 3.5. so both SDK 3.5 and SDK 4.0 artifacts are going to be available.

Migrating Cairngorm libs to Parsley 2.2.2

-Change initialization objects of Cairngorm Parsley extensions to Parsley convention (i.e. CairngormModuleLib>CairngormModuleSupport). Every initialization object has a static initialize method and implements Parsley's ContextBuilderProcessor, which allows it to be specified within a ContextBuilder definition.
-API Change in Navigation library: Changed -FirstEnter metadata to Enter(time="first"), -Enter metadata to Enter(time="next") and -EveryEnter metadata to Enter(time="every")
-Added convenience isValid get accessor to ValidationGroupEvent

-Completed module runtime support. (allows the description of modules and interceptors in XML loaded at runtime)
-Revert temporarily switching to Parsley snapshot version 2.2.2 (back on 2.2.0 until the official 2.2.2 release)

-Added experimental version (not working yet) of module runtime support (allows the description of modules and interceptors in XML loaded at runtime)
-Temporarily switching to Parsley snapshot version 2.2.2

- Fixing a bug in the case where a Message is dispatched without a ModuleId defined to a Module type which is not yet instantiated.
- Updating the sample to show this use-case.
