Silk Road Powertoys

Change goal : to enable caching of image query requests on the web service

LiveSearchApiPowerToysComponents : Query.cs class
Added CacheIdentifier and CacheExpirationInterval Properties, and updated constructor.

LiveSearchApiPowerToysComponents : ImageQuery.cs class
Refactored methods previously developed within the imageshelper web service to execute live search query and process retrieved images and errors.
This way these methods can be executed in code other than the web service

LiveSearchPowerToysWeb: imageshelper.cs class
Enabled caching and used factored out the request to LiveSearch API based on new features in ImageQuery class

WebControls : ImageSearchSlideShow.cs
Removed use of ViewState for implementation of control's properties
Reviewed properties implementation and attribute definitions
Added CacheExpirationInterval and CacheIdentifier to the control

WebControls : Properties/AssemblyInfo.cs : fixed compilation error

Added XML documentation to all classes and methods. The whole solution is now StyleCop clean
